<h2>Summary</h2>

 This article is the third activity report in the context of the participatory research project <a href="/@lemouth/towards-a-citizen-science-particle-physics-research-project-on-hive">Citizen science particle physics project on Hive</a> led by @lemouth and undertaken by a number of blockchain enthusiasts. In it we will see the realization of the project tasks concerning _detector effects and event reconstruction_. The instructions laid out in <a href="/@lemouth/citizen-science-on-hive-simulating-top-quark-production-at-cern-s-large-hadron-collider">this article</a> have been followed. In the first attempt there were some exceptions related to the generation of PDF and DVI files. Configuration differences were also noticed when comparing with the tutorial in the mentioned article. An output HTML document could be obtained, but without the expected histogram. I ask @lemouth to please review my procedures in order to correct them and make the corresponding updates.

<hr>

<h3>Task 1: Getting started with MadAnalysis 5</h3>

In order to simulate the particle physics detector such as the one at CERN, it is necessary to install MadAnalysis5. To do this I ran <code>git clone https://github.com/MadAnalysis/madanalysis5</code> to download the source code, which can be run immediately.

<div class="text-center"><img src="https://images.hive.blog/DQmeb9B5LHp9WR5w393X4zbTt8Fnn6oYZBVUhG1ShdwNuF6/C1.png" alt="Downloading MadAnalysis5 from GitHub according to the instructions">
<br><sup><b>⬆️ Image 1:</b> Downloading MadAnalysis5 from GitHub according to the instructions.</sup></div>

However, when executing it, the program throws an exception since the "python" command is not understood by the system. This tells me that the software needs to access Python using that alias. Since my GNU/Linux distribution installation only uses the <code>python3</code> alias, I had to do some configuration tweaking following the instructions at <a href='https://unix.stackexchange.com/questions /675430/i-messed-up-trying-to-set-python3-as-default-on-linux-mint'>this post</a> to create that alias and have <code>python</code> call to the Python 3 program. Once that was done, MadAnalysis5 ran normally.

<div class="text-center"><img src="https://images.hive.blog/DQmdjkP2r5JucQR8D6yfFqJDy1XJvPH5aejdUc6WRCjnyjK/C3.png" alt="MadAnalysis5 is working fine">
<br><sup><b>⬆️ Image 2:</b> MadAnalysis5 is working fine.</sup></div>

Then a series of compilations begins, which is normal according to the instructions. In the end I get this output:

<div class="text-center"><img src="https://images.hive.blog/DQmWbFVvJH5s5mnpcqdnEuDpbWMvfNYV7gpDpBjbeXgr9TN/C5.png" alt="Output">
<br><sup><b>⬆️ Image 3:</b> Output.</sup></div>

Comparing to @lemouth's tutorial I can see there are differences. On my system the SciPy, pyhf and matplotlib packages are disabled. Since the instructions indicate that matplotlib is crucial, I decided to install it, a little bit late though, that is, after the other procedures. In the end I realized I had done something wrong and found out what this was, so I installed matplotlib for the whole system.

<h3>Task 2: Additional packages</h3>

I installed zlib and fastjet using <code>install zlib</code> and, after restarting MadAnalysis5, I used <code>install fastjet</code> (funny names by the way).

<div class="text-center"><img src="https://images.hive.blog/DQmVMEq7pNtE3f2RWuWwhESvmntfcEBqQhN2ZTGJeRoJ68B/C6.png" alt="Zlib installed">
<br><sup><b>⬆️ Image 4:</b> Installed zlib. You can see that matplotlib is still marked as disabled, since I didn't notice it yet.</sup></div>

<div class="text-center"><img src="https://images.hive.blog/DQmXgZ6c1B4yxeT52JFo6j22GnUDLtqUep67S2ewB3rU4rV/C7.png" alt="Installed zlib and fastjet">
<br><sup><b>⬆️ Image 5:</b> Installed zlib and fastjet and restarted MadAnalysis5 once again.</sup></div>

Around this time I realized I would need matplotlib and installed it. I started MadAnalysis5 again and the log already showed matplotlib as enabled. However, PySci is still disabled since I installed MadAnalysis5. I hope that won't be a problem.

<div class="text-center"><img src="https://images.hive.blog/DQmXLvnctgybT8CCXbkmoeHnopGcyU1bWyXxKVGEcPzZwyv/C8.png" alt="Matplotlib ya está instalado y enabled">
<br><sup><b>⬆️ Image 6:</b> Matplotlib is already installed and enabled.</sup></div>

<h3>Task 3: Top-antitop simulations</h3>

I'm still getting ready to do some physics. I copied the path to the file tag_1_pythia8_events.hepmc.gz generated with the past activity and then restarted Ma5 with <code>./bin/ma5 -R madanalysis/input/ATLAS_default.ma5</code>. I ran the other instructions (<code>import <path-to-my-events></code>, <code>set main.outputfile=myeventstoo.lhe.gz</code> and <code>submit</code>) . This took a while to run, but in the end I got this output:

<div class="text-center"><img src="https://images.hive.blog/DQmNucGhr2Ptx2SZtQKiTU3P86SghtSmQwBvPXSEJmSAo21/C9.png" alt="Output">
<br><sup><b>⬆️ Image 7:</b> Oops, there are some issues.</sup></div>

As we can see, some things did not go well. It did generate a file of approximately 7mb as expected based on the instructions, but neither the PDF nor the DVI file was generated. I thought this might be because I didn't have SciPy installed, so I installed it by following <a href='https://scipy.org/install/'>this documentation</a>. However, repeating the process did not fix the problem. I checked the suggested log and there seems to be a problem with Latex.

<div class="text-center"><img src="https://images.hive.blog/DQmYECauTUYCEKNe3oBP74speTzCfsbX11GYtVJT8ikr38s/C10.png" alt="There it is">
<br><sup><b>⬆️ Image 8:</b> There it is. The file was generated as expected.</sup></div>

<div class="text-center"><img src="https://images.hive.blog/DQmb8DjTNuNBexbiNY1itnF3PgR8AvFStmcvhzrGzAPKMid/C11.png" alt="">
<br><sup><b>⬆️ Image 9:</b> And this is the log output (.../madanalysis5/ANALYSIS_3/Output/PDF/MadAnalysis5job_0/latex2.log)</sup></div>

As indicated in the log, there is a problem with the pdftexcmds.sty package. According to what I googled, that package comes separately in the most recent versions of Tex Live or something like that, so it would have to be installed separately. However, I didn't know how to fix this easily. Apparently I need to do a <a href='http://www1.coe.neu.edu/~jkimani/Latex1.html'>full TexLive install</a>, but if I understand correctly, that would take about 5 GB of extra space. Did I understand correctly? Is all this really necessary? Why does MadAnalysis5 indicate that the latex and pdflatex packages are enabled and yet the log indicates something else (see image 5)? This is a bit confusing :S

Similarly, the log for the DVI files gave this:

<pre>
! LaTeX Error: File `pdftexcmds.sty' not found.

Type X to quit or &#60;RETURN&gt; to proceed,
or enter new name. (Default extension: sty)

Enter file name: 
! Emergency stop.
&#60;read *&gt; 
         
l.108 \RequirePackage{pdftexcmds}[2009/04/10]
                                             ^^M
No pages of output.
Transcript written on main.log.
</pre>

Which is basically the same exception.

<h3>Task 3: Some physics</h3>

I decided to go ahead and see if this could work after all. I ran the commands:

<pre><code>import ANALYSIS_0/Output/SAF/_defaultset/lheEvents0_0/myeventstoo.lhe.gz as ttbar
set ttbar.xsection = 505.491
plot NAPID
submit</code></pre>

<br>

<div class="text-center"><img src="https://images.hive.blog/DQmShdyxGZTmjJdDMxy1uxZCN4DCENE7PbecNBvAPrMaBH7/Cinput.png" alt="Entering the commands to do some physics">
<br><sup><b>⬆️ Image 10:</b> Entering the commands to do some physics.</sup></div>

And after a short wait I got this output:

<div class="text-center"><img src="https://images.hive.blog/DQmUnyoUAArEMDQ6KLM4A5TSoCzFpPieMNc6RC53jhs9Vbt/Coutput.png" alt="An alarming output?">
<br><sup><b>⬆️ Image 11:</b> An alarming output?</sup></div>

Again the same exceptions appeared regarding the generation of PDF and DVI files. An HTML document was generated and using the <code>Open</code> command, as suggested by the output, opened the web browser displaying this page:

<div class="text-center"><img src="https://images.hive.blog/DQmXWGX1aJHUDtW1npj33kNtoWtHVebgSKdqqsZ7zTMaj34/Copen.png" alt="HTML document generated">
<br><sup><b>⬆️ Image 12:</b> HTML document generated.</sup></div>

The _histos and cuts_ part was empty, a histogram plot was not generated as expected.

At the moment this is what I have. I hope @lemouth you can help me fix these issues and get the histogram generated. Thanks in advance.

<h2>UPDATE 2022/04/26:</h2>

Finally I have obtained the expected outputs. Getting to this was quite a "journey" that had many stops and definitely deserves its own post. Essentially I had to get another computer where I could fully install TexLive (2022), reinstall and repeat all the tasks of this project from scratch and read a lot of documentation and support forums to overcome every exception that appeared. But it was worth it!

<div class="text-center"><img src="https://images.hive.blog/DQmdFM6MDVxhHiDGfSgxxY7sEaaFR9bumTKtXSCiaLoGP9h/success.png" alt="At last!">
<br><sup><b>⬆️ Image 13:</b> The expected output, no errors.</sup></div>

<div class="text-center"><img src="https://images.hive.blog/DQmRtgppqZS3Uw4V4rYuL74vTtQ4QS5B8kjsZUxquHjY2M4/report.png" alt="Histogram generated">

Thanks to @lemouth for his feedback.

<h2>Resumen</h2>

Este artículo es el tercer reporte de actividades en el contexto del proyecto de investigación participativa <a href="/@lemouth/towards-a-citizen-science-particle-physics-research-project-on-hive">Citizen science particle physics project on Hive</a> dirigido por @lemouth y emprendido por una serie de entusiastas de la blockchain. En él veremos la realización de las tareas de proyecto en lo referido a los _efectos de los detectores y reconstrucción de eventos_. Se han seguido las instrucciones planteadas en <a href="/@lemouth/citizen-science-on-hive-simulating-top-quark-production-at-cern-s-large-hadron-collider">este artículo</a>. En el primer intento se produjeron unas excepciones relacionadas con la generación de archivos PDF y DVI. También se apreciaron diferencias de configuración al comparar con el tutorial en el artículo mencionado. Se pudo obtener un documento HTML de salida, pero sin el histograma esperado. Agradezco a @lemouth la revisión de mis procedimientos a fin de corregirlos y hacer las actualizaciones correspondientes.

<hr>

<h3>Tarea 1: Empezar a utilizar MadAnalysis 5</h3>

Para poder hacer la simulación del detector de física de partículas tal como el del CERN es necesario instalar MadAnalysis5. Para ello ejecuté <code>git clone https://github.com/MadAnalysis/madanalysis5</code> para descargar el código fuente, que puede ser ejecutado inmediatamente.

<div class="text-center"><img src="https://images.hive.blog/DQmeb9B5LHp9WR5w393X4zbTt8Fnn6oYZBVUhG1ShdwNuF6/C1.png" alt="Descargando MadAnalysis5 de GitHub según las instrucciones.">
<br><sup><b>⬆️ Imagen 1:</b> Descargando MadAnalysis5 de GitHub según las instrucciones.</sup></div>

Sin embargo, al ejecutarlo el programa produce excepción puesto que la orden "python" no es entendida por el sistema. Esto me indica que el software necesita acceder a Python usando ese alias. Dado que la instalación de mi distribución GNU/Linux solo usa el alias <code>python3</code>, tuve que hacer unos ajuste de configuración siguiendo las instrucciones en <a href='https://unix.stackexchange.com/questions/675430/i-messed-up-trying-to-set-python3-as-default-on-linux-mint'>este post</a> para crear ese alias y hacer que <code>python</code> invoque al programa Python 3. Una vez hecho eso, MadAnalysis5 se ejecutó normalmente.

<div class="text-center"><img src="https://images.hive.blog/DQmdjkP2r5JucQR8D6yfFqJDy1XJvPH5aejdUc6WRCjnyjK/C3.png" alt="MadAnalysis5 funcionando bien">
<br><sup><b>⬆️ Imagen 2:</b> MadAnalysis5 funcionando bien.</sup></div>

Acto seguido empieza una serie de compilaciones, lo cual es normal de acuerdo a las instrucciones. Al final obtengo esta salida:

<div class="text-center"><img src="https://images.hive.blog/DQmWbFVvJH5s5mnpcqdnEuDpbWMvfNYV7gpDpBjbeXgr9TN/C5.png" alt="Salida tras las compilaciones">
<br><sup><b>⬆️ Imagen 3:</b> Salida tras las compilaciones.</sup></div>

Al comparar con el tutorial de @lemouth, puedo ver que hay diferencias. En mi sistema, los paquetes SciPy, pyhf y matplotlib están deshabilitados. Dado que las instrucciones indican que matplotlib es crucial, decidí instalarlo, aunque tardíamente, es decir, después de los demás procedimientos. Al final me di cuenta que había hecho algo mal y descubrí que era esto, por lo que instalé matplotlib para todo el sistema.

<h3>Tarea 2: Paquetes adicionales</h3>

Instalé zlib y fastjet usando <code>install zlib</code> y, tras el reinicio de MadAnalysis5, <code>install fastjet</code> (curiosos nombres por cierto).

<div class="text-center"><img src="https://images.hive.blog/DQmVMEq7pNtE3f2RWuWwhESvmntfcEBqQhN2ZTGJeRoJ68B/C6.png" alt="Instalado zlib">
<br><sup><b>⬆️ Imagen 4:</b> Instalado zlib. Puede verse que matplotlib sigue marcado como disabled, puesto que aún no lo notaba.</sup></div>

<div class="text-center"><img src="https://images.hive.blog/DQmXgZ6c1B4yxeT52JFo6j22GnUDLtqUep67S2ewB3rU4rV/C7.png" alt="">
<br><sup><b>⬆️ Imagen 5:</b> Inslaldos zlib y fastjet y reiniciado MadAnalysis5 una vez mas.</sup></div>

Alrededor de este momento me di cuenta que necesitaría matplotlib y lo instalé. Inicié nuevamente MadAnalysis5 y el log ya me mostraba a matplotlib como enabled. Sin embargo, PySci sigue deshabilitado desde que hice la isntalación de MadAnalysis5. Espero que eso no vaya a ser un problema.

<div class="text-center"><img src="https://images.hive.blog/DQmXLvnctgybT8CCXbkmoeHnopGcyU1bWyXxKVGEcPzZwyv/C8.png" alt="Matplotlib ya está instalado y marcado como enabled">
<br><sup><b>⬆️ Imagen 6:</b> Matplotlib ya está instalado y marcado como enabled.</sup></div>

<h3>Tarea 3: Simulaciones de top-antitop</h3>

Sigo preparándome para hacer algo de física. Copié la ruta al archivo tag_1_pythia8_events.hepmc.gz generado con la actividad pasada y acto seguido reinicié a Ma5 con <code>./bin/ma5 -R madanalysis/input/ATLAS_default.ma5</code>. Ejecuté las demás instrucciones (<code>import <path-to-my-events></code>, <code>set main.outputfile=myeventstoo.lhe.gz</code> y <code>submit</code>). Esto tardó algo en ejecutarse, pero al final obtuve esta salida:

<div class="text-center"><img src="https://images.hive.blog/DQmNucGhr2Ptx2SZtQKiTU3P86SghtSmQwBvPXSEJmSAo21/C9.png" alt="Ups, hay problemas">
<br><sup><b>⬆️ Imagen 7:</b> Ups, hay problemas.</sup></div>

Como podemos ver, algunas cosas no salieron bien. Sí se generó un archivo de aproximadamente 7 mb tal como se esperaba según las instrucciones, pero no se generó el PDF ni el archivo DVI. Pensé que esto podía tener que ver con que no tenía SciPy instalado, así que lo instalé siguiendo <a href='https://scipy.org/install/'>esta documentación</a>. Sin embargo, al repetir el proceso, esto no solucionó el problema. Verifiqué el log sugerido y al parecer hay un problema con Latex.

<div class="text-center"><img src="https://images.hive.blog/DQmYECauTUYCEKNe3oBP74speTzCfsbX11GYtVJT8ikr38s/C10.png" alt="Allí está">
<br><sup><b>⬆️ Imagen 8:</b> Allí está. El archivo generado como se esperaba.</sup></div>

<div class="text-center"><img src="https://images.hive.blog/DQmb8DjTNuNBexbiNY1itnF3PgR8AvFStmcvhzrGzAPKMid/C11.png" alt="Y esta es la salida del log">
<br><sup><b>⬆️ Imagen 9:</b> Y esta es la salida del log (.../madanalysis5/ANALYSIS_3/Output/PDF/MadAnalysis5job_0/latex2.log).</sup></div>

Como se indica en el log, hay un problema con el paquete pdftexcmds.sty. Según googleé, ese paquete viene separado en las versiones más recientes de Tex Live o algo por el estilo, por lo que habría que instalarlo separadamente. Sin embargo, no supe cómo solucionar esto de manera sencilla. Al parecer debo hacer una <a href='http://www1.coe.neu.edu/~jkimani/Latex1.html'>instalación completa de TexLive</a>, pero si entendí bien, ello necesitaría como 5 GB de espacio adicional. ¿Entendí bien? ¿Es realmente todo esto necesario? ¿Por qué MadAnalysis5 indica que los paquetes latex y pdflatex están habilitados y sin embargo el log indica otra cosa (ver imagen 5)? Esto es un poco confuso :S

Similarmente, el log para los archivos DVI arrojó esto:

<pre>
! LaTeX Error: File `pdftexcmds.sty' not found.

Type X to quit or &#60;RETURN&gt; to proceed,
or enter new name. (Default extension: sty)

Enter file name: 
! Emergency stop.

l.108 \RequirePackage{pdftexcmds}[2009/04/10]
                                             ^^M
No pages of output.
Transcript written on main.log.
</pre>

Que es básicamente la misma excepción.

<h3>Tarea 4: Algo de física</h3>

Decidí seguir adelante para ver si esto podía funcionar después de todo. Ejecuté los comandos:

<pre><code>import ANALYSIS_0/Output/SAF/_defaultset/lheEvents0_0/myeventstoo.lhe.gz as ttbar
set ttbar.xsection = 505.491
plot NAPID
submit</code></pre>

<br>

<div class="text-center"><img src="https://images.hive.blog/DQmShdyxGZTmjJdDMxy1uxZCN4DCENE7PbecNBvAPrMaBH7/Cinput.png" alt="Ingresando los comandos para hacer algo de física">
<br><sup><b>⬆️ Imagen 10:</b> Ingresando los comandos para hacer algo de física.</sup></div>

Y tras una breve espera obtuve esta salida:

<div class="text-center"><img src="https://images.hive.blog/DQmUnyoUAArEMDQ6KLM4A5TSoCzFpPieMNc6RC53jhs9Vbt/Coutput.png" alt="¿Una salida alarmante?">
<br><sup><b>⬆️ Image 11:</b> ¿Una salida alarmante?</sup></div>

Nuevamente aparecieron las mismas excepciones con respecto a la generacion de los archivos PDF y DVI. Si se generó un documento HTML y al usar el comando <code>Open</code>, como sugiere la salida, se abrió el navegador web mostrando esta página:

<div class="text-center"><img src="https://images.hive.blog/DQmXWGX1aJHUDtW1npj33kNtoWtHVebgSKdqqsZ7zTMaj34/Copen.png" alt="Documento HTML generado">
<br><sup><b>⬆️ Imagen 12:</b> Documento HTML generado.</sup></div>

La parte de _histos and cuts_ estaba vacía, no se generó un gráfico de histograma como se esperaba.

De momento esto es lo que tengo. Espero, @lemouth, puedas ayudarme a solucionar estos problemas y conseguir que se genere el histograma.

<h2>ACTUALIZACIÓN 2022/04/26:</h2>

Finalmente he conseguido las salidas esperadas. Llegar a esto consitió en toda una "travesía" que tuvo muchas paradas y que definitivamente merece su propio post. Esencialmente tuve que conseguirme otra computadora donde poder instalar completamente TexLive (2022), reinstalar y repetir todas las tareas de este proyecto desde cero y leer mucha documentación y foros de soporte para superar cuanta excepción aparecía. ¡Pero ha valido la pena!

<div class="text-center"><img src="https://images.hive.blog/DQmdFM6MDVxhHiDGfSgxxY7sEaaFR9bumTKtXSCiaLoGP9h/success.png" alt="Por fin">
<br><sup><b>⬆️ Image 13:</b> La salida esperada, sin errores.</sup></div>

<div class="text-center"><img src="https://images.hive.blog/DQmRtgppqZS3Uw4V4rYuL74vTtQ4QS5B8kjsZUxquHjY2M4/report.png" alt="Histograma generado">
<br><sup><b>⬆️ Image 14:</b> Histograma generado.</sup></div>

Gracias a @lemouth por su feedback.

You guys are better than me. I sweat a bit before getting it done. I never bothered about installing latex or pdf since I got an info earlier that one can proceed without it.

It's great that you got it done! In my case, both of them are causing problems.

Hi eniolw. Apologies for the delay in reviewing this report. Easter was in the way ;)

First of all, thanks a lot for this report and your hard work! Let's now work together to fix your issues.

> However, when executing it, the program throws an exception since the "python" command is not understood by the system

Mmmh that is a good remark. I should add something with this respect in the main post, or maybe replace <code>#!/usr/bin/env python3</code> by <code>#!/usr/bin/env python3</code> in the <code>bin/ma5</code> file. I will start by dealing with the former as it is easier.

>  However, PySci is still disabled since I installed MadAnalysis5. I hope that won't be a problem.

Nope, this won’t be an issue. Otherwise, you can still install it later via <code>pip3</code> for instance.

> However, I didn't know how to fix this easily. Apparently I need to do a full TexLive install, but if I understand correctly, that would take about 5 GB of extra space. Did I understand correctly?

Hmmmm I didn’t know this. I have opened an issue on GitHub (<a href='https://github.com/MadAnalysis/madanalysis5/issues/69'>here</a>), so that me or anyone from the MadAnalysis5 team will check this out very soon. 

In the meantime, this is not a big deal if latex is disabled (you can just veto its usage it by editing the file <code>madanalysis/input/installation_options.dat</code>, un-commenting the related lines (49 and 52) and setting the veto to true (<code>1</code>).

> At the moment this is what I have. I hope @lemouth you can help me fix these issues and get the histogram generated. Thanks in advance.

It seems that some fonts required by matplotlib are not available, at least according to the error message. Do you mind installing them and retrying? Please let me know whether this works.

Cheers!
