'''Getting a histo from GEMC ROOT data'''
 +
<pre>
 +
To get a histogram from GEMC data do something akin to:
 +
  TH2F *edep_p = new TH2F("edep_p","edep vs p (Protons)",100,0.0,4000.0,100,0.0,2.2);
 +
  edep_p->SetMarkerColor(40); 
 +
  edep_p->SetMarkerSize(20.0);
 +
  bst->Draw("Edep:p>>edep_p","Edep<2");
 +
First we create the histo, set up some attributes, and then finally we pipe a graph into
 +
it. After this, you probably want to use Clear() in whatever pad your using to remove
 +
any graphs it draws in the process.
 +
</pre>
 +
 
 +
'''Specifying exactly which histo to grab'''
 +
<pre>
 +
In something like:
 +
  bst->Draw("Edep:p","Edep<2");
 +
Edep may be in the bst tree while p is in the generated tree. To specify which ones to use:
 +
  bst->Draw("Edep:genT.p","Edep<2");
 +
</pre>
 +
 
 +
'''Drawing A Legend'''
 +
<pre>
 +
Try something like:
 +
  TLegend *leg = new TLegend(0.4,0.6,0.89,0.89);
 +
  leg->SetTextSize(.03);
 +
  leg->AddEntry(histo,"title","p"); //p specifies marker as key
 +
  leg->SetFillColor(0); //white BG instead of yellow default
 +
  leg->Draw();
 +
And to change the marker color of a histo:
 +
  histo->SetMarkerColor(int color);
 +
</pre>

 +
====June====
 +
'''Wed 4'''
 +
<pre>
 +
In 12:00pm
 +
Sarah gave Dan and I example root scripts which we are to modify for use with data collected in GEMC.
 +
Can now open root files from interpreter or program, explore trees and draw histos. I want to be able
 +
to recreate some of these: http://clasweb.jlab.org/wiki/index.php/First_SVT_results
 +
Out 4:00pm
 +
</pre>
 +
 
 +
'''Thur 5'''
 +
<pre>
 +
In 1:00pm
 +
Made theta dependence event detection graph. Recreated Edep vs. p graph using AddFriend method on TTree svt.
 +
Then everything took a strange turn as root began to fail to do things. Worked with sarah trying to figure
 +
out what was going on. Affecting different programs, different versions of root.
 +
Out 4:00pm
 +
</pre>
 +
 
 +
'''Tue 10'''
 +
<pre>
 +
In 1:00pm
 +
Met with Sarah, Maurik. Frustratingly tried to manipulate GEMC data trees. Finally reached the point
 +
where we can create copies of histograms. Many root things not working or working strangely.
 +
Need to get bin content of individual histos and manipulate them manually.
 +
Out 4:00pm
 +
</pre>
 +
 
 +
'''Wed 11'''
 +
<pre>
 +
In 12:00pm
 +
Trying to create one 2d histogram from two 1d histograms...can't find anything similar online.
 +
Maurizio got back to us, piped output into a 2d histogram and it worked. Changed drawing,
 +
binning options. Looks great! Dan is running a 50000 event simulation with the same inputs
 +
as our current 5000 event data for further refined data.
 +
 
 +
gemc_evio2root has been updated and our current version of root does not have RIO libraries.
 +
Another version did but we found it to be incompatible.
 +
Out 3:45pm
 +
</pre>
 +
 
 +
'''Wed 18'''
 +
<pre>
 +
In 2:00pm
 +
The hub is not working, Hovannes, Dan and I tried to get ennui and benfranklin up to no avail.
 +
Hovannes and I just used our laptops, with Dan on benfranklin going direct to an ethernet jack in the wall.
 +
Talked to sarah, recreating graphs. Have Edep v. p, working on theta with threshold cutting and phi v. z.
 +
Our Phi v. z plot is very sparsely populated. I emailed maurizio about this.
 +
One can see two distinct signals in the proton & pion edep v p graph, however we may need to widen
 +
our energy scale (lower) to see this more clearly. Running simulation with wider energy allowances.
 +
Out 5:00pm
 +
</pre>
 +
 
 +
'''Tue 24'''
 +
<pre>
 +
In 1:00
 +
Elog is up but needs a proper template - Dan is on that. Making images of the graphs to put in elog. Fixed wiki log error.
 +
Running 500,000 events proton and pion simultaneously. Need more statistics to replicate Maurizio's graphs. Proton data was
 +
damaged and I am running it again. Running another pion experiment to add to our current one.
 +
Out 3:30
 +
Ran to James hall fossil/map giveaway
 +
In 4:15
 +
Creating pion-proton graph with new data
 +
Out 4:30
 +
</pre>
 +
 
 +
'''Thur 26'''
 +
<pre>
 +
In 11:15am
 +
Working on pion-proton graph.
 +
Out 12:00pm Lunch
 +
 
 +
In 1:15
 +
Had Katie sign timesheets
 +
I cannot figure out why our data isn't succesfully piping to histograms.
 +
Talked to sarah, she didn't know. Checking root documentation.
 +
Can we directly refer to histograms?
 +
Out 4:30
 +
</pre>
 +
 
 +
'''Mon 30'''
 +
<pre>
 +
In 12:15
 +
Contacted jlab, my password has changed and I can't svn or get my email.
 +
Dan gone until tommorow, he's in NJ. I shall investigate why my program
 +
isn't working.
 +
Finally fixed the pion & proton edep_p graph! Cool!
 +
Updated some wiki information on availability and versions of programs
 +
in the CLAS12ROOT directory. Created a notes section for me, in this log.
 +
Updated summer, fall schedule.
 +
 
 +
Made theta graph with current data. Maurizio's cuts are different than mine.
 +
Making phi vs. z graph. I need to combine lots of data for a statistical view,
 +
running more proton simulations.
 +
Out 3:15pm
 +
</pre>
 +
 
 +
====July====
 +
'''Tue 1st'''
 +
<pre>
 +
In 1:30pm
 +
Organized goals with Sarah. Dan has elog running on mariecurie, but does Maurik want
 +
us using it? Emailing maurizio for coordinate system and other things.
 +
Maurizio got back to us. /home ran out of space! We alerted matt and spoke with him
 +
about the new server. Organized CLAS12ROOT. Data will now be in CLAS12ROOT/Experiments/data
 +
to keep home directories smaller. Removed older data.
 +
Out 4:45pm
 +
</pre>
 +
 
 +
'''Thur 3rd'''
 +
<pre>
 +
In 7:45am
 +
Edited RHEL5_x64 env script to reflect a new $DATA variable pointing to the folder containing
 +
all the data from gemc runs.
 +
 
 +
The data I set running Tue 1st seems to have not been properly closed. Someone must have killed
 +
benfranklin's internet connection before my run finished last night. Rerunning.
 +
 
 +
I created an Index.txt in $DATA in which we can keep the command used to generate data next to
 +
it's filename, alleviating the need for long rootfile names.
 +
 
 +
I don't understand why we register so few hits in layers 2, 3, and 4 in our data, for the theta
 +
graph. You can see it again, in the Edep graphs.
 +
 
 +
I do not know the cause of the phenomenon, but I nearly sure there are 8 layers in total between
 +
all four barrels of the SVT. I would think this would mean 2 per layer but histograms I have
 +
generated beg to differ. Made x_y_z for all 8 layers.
 +
Out 10:30am
 +
</pre>
 +
 
 +
'''Thur 10th'''
 +
<pre>
 +
In 12:00pm
 +
Hobo and Ben Franklin are not of good health, so Dan and I are using the physics lounge computers.
 +
We asked maurizio about the layers confusion and it works as such:
 +
 
 +
"layer[0] == 1 means "plot all events where the first hit was in layer 1".
 +
layer[1] == 2 means "plot all events where the second hit was in layer 2"  - that means the first hit is somewhere else
 +
layer[4] == 3 means "plot all events where the fifth hit was in layer 3"  - that means the first 4 hits are somewhere else (very unlikely)."
 +
 
 +
So my question is how do I specify showing the hits in just a single layer?
 +
out 2:45
 +
</pre>
 +
 
 +
'''Tue 15th'''
 +
<pre>
 +
In 1:00
 +
Prepared for meeting with Maurik. Fixed X_Y_Z graph.
 +
Lunch 2:45
 +
In 3:45
 +
Looking through gemc's output code. Trying to find evio documentation.
 +
Out 4:30
 +
</pre>
 +
 
 +
'''16th-19th'''
 +
<pre>
 +
Trying to decipher GEMC and gemc2evio code. Just following it, not producing anything
 +
so I'm not recording any hours.
 +
</pre>
 +
 
 +
'''Tue 22'''
 +
<pre>
 +
In 1:00
 +
Checking out GEMC code. Trying to form questions to ask Maurik.
 +
Out 2:00
 +
 
 +
Our advisors were busy! Reading code. Perhaps if we can create our own dummy item in gemc and
 +
run it through the processes until we can see it in a root file we will understand more.
 +
</pre>
 +
 
 +
'''Thur 24'''
 +
<pre>
 +
In 3:00pm
 +
Did timesheets for past two weeks.
 +
Inside output/evio_output.cc is an interesting method, called WriteGenerated, which takes a vector<MGeneratedParticle>
 +
called MGP. I'm trying to find where WriteGenerated is called to see where MGP originates.
 +
 
 +
WriteGenerated is referenced in src/MEventAction.cc
 +
 
 +
More interesting things inside /hitprocess/clas12/svt/BST_hitprocess.cc

 +
 
 +
'''Mon 28'''
 +
<pre>
 +
Came in at 12:15 but the physics lounge computers were inaccessable. Tried to boot up BF but it was
 +
taking a long time so I went to an early lunch. Saw Maurik! Meeting with Sarah later. Amrit may have
 +
a student? Also need to coordinate a time to move computers in the nuc server room.
 +
 
 +
In 1:30
 +
Physics lounge still being buffed. Bypassed router in JLAB room, BF booted up fine. It occurred to me
 +
during lunch that MGeneratedParticle is probably a Geant4 object and I can use the G4 documentation.
 +
 
 +
-Strike that. Haven't found anything online. $GEMC/grep -R -i mgeneratedparticle ./
 +
 
 +
Nice find: /src/MHit.cc:

 +
 
 +
Made some changes to GEMC code. MHit.cc and MSensitiveDetector.cc. compiled, but not putting my changes into the output.

'''Move Week'''
 +
<pre>
 +
Dan and I were here Mon-Thur for 8-9 hours a day helping, but I'm not sure if it's work or not.
 +
We recorded three hours a day, will check with sarah.
 +
</pre>
 +
 
 +
'''Mon 11'''
 +
<pre>
 +
In 11:30
 +
Dan is investigating Elog problems. Sarah has the guidelines for the electrical output methods
 +
that we are to implement, but I am still reading the code, trying to write a variable out.
 +
 
 +
I'm trying to identify a clear chain of events in processing a hit, and writing it out. It's not yet
 +
completely clear where we will need to interrupt this chain to insert our ADC to TDC code
 +
however it has become apparent to me that evio_output.cc has a much higher importance than
 +
I had originally given it in processing and writing an event.
 +
 
 +
2:00 - ran to nesmith, getting a table for dawn.
 +
2:10 - back
  
===In Progress===
+
mariecurie seems to have gone down for some reason. We are trying to transition to Elog.
Batch mode guide comming along well, 80% of what we are doing right now is in the short list at the top. Gui manipulation is coming along with dan. More sections will be added.
 
  
I can put together things already defined like SVTs, but what about single strips? Not implemented yet? XML guide is very basic, clean and clear up a little bit. Cant stress HDDS-1_0.xsd enoung. (In your Sim12 directory) The XML seems like a great system, glad you choose to go with HDDS.
+
Updating GEMC. I will try to get a variable written out through the generated info tree.
  
Reading about detector theory, particle physics. Seiden's 'Particle Physics' in the office, gettting Griffith's. Ask Maurik for book recommendations.
+
Moved desks for Sarah.
  
==Notes==

Pumpkin slow for some reason. Using Einstein.
 +
 
 +
Ok. So I think most of the actual writing and suck happens inside evio_output.cc|Record_and_Clear(). However, I
 +
don't yet speak EVIO and will begin reading EVIO's code more in depth.

In 2:15
 +
Read G4 examples sent by Sarah, Simulation study for a single TOF
 +
scintillator using GEANT4. Brigada's paper was more accessible in the fourth part,
 +
which is directly relevant to our interests. I'd like to see the code as well.

<pre>
 +
In 10:00am
 +
 
 +
Creating a method to write out digital info in GEMC.
 +
Success! It writes out a file called digitalouts.txt. With information like:
 +
 
 +
layer: 1    sector: 5    strip: 18    Edep: 0.215085 MeV
 +
layer: 2    sector: 5    strip: 220    Edep: 0.283442 MeV
 +
layer: 3    sector: 8    strip: 190    Edep: 0.129059 MeV
 +
layer: 3    sector: 8    strip: 191    Edep: 0.177371 MeV
 +
layer: 4    sector: 8    strip: 13    Edep: 0.255779 MeV
 +
layer: 5    sector: 10    strip: 17    Edep: 0.172112 MeV
 +
layer: 6    sector: 10    strip: 170    Edep: 0.160031 MeV
 +
layer: 7    sector: 14    strip: 58    Edep: 0.153398 MeV
 +
 
 +
Of course, to use this data it is much more likely we will
 +
be organising more like:
 +
 
 +
layer  sector  strip  Edep
 +
1          5            18      .21508
 +
etc
 +
 
 +
In fact, this system is probably not directly suited for
 +
simulated electronics output as we want to integrate
 +
the energy deposited in a strip over a certain amount
 +
of time, and then read that out. Right?

Getting a histo from GEMC ROOT data

To get a histogram from GEMC data do something akin to:
  TH2F *edep_p = new TH2F("edep_p","edep vs p (Protons)",100,0.0,4000.0,100,0.0,2.2);
  edep_p->SetMarkerColor(40);  
  edep_p->SetMarkerSize(20.0); 
  bst->Draw("Edep:p>>edep_p","Edep<2");
First we create the histo, set up some attributes, and then finally we pipe a graph into
it. After this, you probably want to use Clear() in whatever pad your using to remove
any graphs it draws in the process.

Specifying exactly which histo to grab

In something like:
  bst->Draw("Edep:p","Edep<2");
Edep may be in the bst tree while p is in the generated tree. To specify which ones to use:
  bst->Draw("Edep:genT.p","Edep<2");

Drawing A Legend

Try something like:
  TLegend *leg = new TLegend(0.4,0.6,0.89,0.89);
  leg->SetTextSize(.03);	
  leg->AddEntry(histo,"title","p"); //p specifies marker as key
  leg->SetFillColor(0); //white BG instead of yellow default
  leg->Draw();
And to change the marker color of a histo:
  histo->SetMarkerColor(int color);

Sarah gave Dan and I example root scripts which we are to modify for use with data collected in GEMC.
Can now open root files from interpreter or program, explore trees and draw histos. I want to be able
to recreate some of these: http://clasweb.jlab.org/wiki/index.php/First_SVT_results

Made theta dependence event detection graph. Recreated Edep vs. p graph using AddFriend method on TTree svt.
Then everything took a strange turn as root began to fail to do things. Worked with sarah trying to figure 
out what was going on. Affecting different programs, different versions of root.

Tue 10

In 1:00pm
Met with Sarah, Maurik. Frustratingly tried to manipulate GEMC data trees. Finally reached the point 
where we can create copies of histograms. Many root things not working or working strangely. 
Need to get bin content of individual histos and manipulate them manually.
Out 4:00pm

In 12:00pm
Trying to create one 2d histogram from two 1d histograms...can't find anything similar online. 
Maurizio got back to us, piped output into a 2d histogram and it worked. Changed drawing, 
binning options. Looks great! Dan is running a 50000 event simulation with the same inputs 
as our current 5000 event data for further refined data.

gemc_evio2root has been updated and our current version of root does not have RIO libraries.
 Another version did but we found it to be incompatible.

The hub is not working, Hovannes, Dan and I tried to get ennui and benfranklin up to no avail. 
Hovannes and I just used our laptops, with Dan on benfranklin going direct to an ethernet jack in the wall.
Talked to sarah, recreating graphs. Have Edep v. p, working on theta with threshold cutting and phi v. z. 
Our Phi v. z plot is very sparsely populated. I emailed maurizio about this.
One can see two distinct signals in the proton & pion edep v p graph, however we may need to widen
 our energy scale (lower) to see this more clearly. Running simulation with wider energy allowances.

Updated summer, fall schedule.

Made theta graph with current data. Maurizio's cuts are different than mine.
Making phi vs. z graph. I need to combine lots of data for a statistical view,
running more proton simulations.

Organized goals with Sarah. Dan has elog running on mariecurie, but does Maurik want
us using it? Emailing maurizio for coordinate system and other things.
Maurizio got back to us. /home ran out of space! We alerted matt and spoke with him
about the new server. Organized CLAS12ROOT. Data will now be in CLAS12ROOT/Experiments/data
to keep home directories smaller. Removed older data.
Out 4:45pm

Thur 3rd

In 7:45am
Edited RHEL5_x64 env script to reflect a new $DATA variable pointing to the folder containing
all the data from gemc runs.

The data I set running Tue 1st seems to have not been properly closed. Someone must have killed
benfranklin's internet connection before my run finished last night. Rerunning.

I created an Index.txt in $DATA in which we can keep the command used to generate data next to
it's filename, alleviating the need for long rootfile names.

I don't understand why we register so few hits in layers 2, 3, and 4 in our data, for the theta
graph. You can see it again, in the Edep graphs. 

I do not know the cause of the phenomenon, but I nearly sure there are 8 layers in total between
all four barrels of the SVT. I would think this would mean 2 per layer but histograms I have
generated beg to differ. Made x_y_z for all 8 layers.
Out 10:30am

Thur 10th

In 12:00pm
Hobo and Ben Franklin are not of good health, so Dan and I are using the physics lounge computers. 
We asked maurizio about the layers confusion and it works as such:

"layer[0] == 1 means "plot all events where the first hit was in layer 1".
layer[1] == 2 means "plot all events where the second hit was in layer 2"  - that means the first hit is somewhere else
layer[4] == 3 means "plot all events where the fifth hit was in layer 3"  - that means the first 4 hits are somewhere else (very unlikely)."

So my question is how do I specify showing the hits in just a single layer?

Did timesheets for past two weeks.
Inside output/evio_output.cc is an interesting method, called WriteGenerated, which takes a vector<MGeneratedParticle>

Came in at 12:15 but the physics lounge computers were inaccessable. Tried to boot up BF but it was 
taking a long time so I went to an early lunch. Saw Maurik! Meeting with Sarah later. Amrit may have
a student? Also need to coordinate a time to move computers in the nuc server room.

In 1:30
Physics lounge still being buffed. Bypassed router in JLAB room, BF booted up fine. It occurred to me
during lunch that MGeneratedParticle is probably a Geant4 object and I can use the G4 documentation.

-Strike that. Haven't found anything online. $GEMC/grep -R -i mgeneratedparticle ./ 

Nice find: /src/MHit.cc:

Dan and I were here Mon-Thur for 8-9 hours a day helping, but I'm not sure if it's work or not. 
We recorded three hours a day, will check with sarah.

Mon 11

In 11:30
Dan is investigating Elog problems. Sarah has the guidelines for the electrical output methods 
that we are to implement, but I am still reading the code, trying to write a variable out.

I'm trying to identify a clear chain of events in processing a hit, and writing it out. It's not yet
completely clear where we will need to interrupt this chain to insert our ADC to TDC code
however it has become apparent to me that evio_output.cc has a much higher importance than
I had originally given it in processing and writing an event.

2:00 - ran to nesmith, getting a table for dawn.
2:10 - back

mariecurie seems to have gone down for some reason. We are trying to transition to Elog.

Creating a method to write out digital info in GEMC.
Success! It writes out a file called digitalouts.txt. With information like:

layer: 1    sector: 5    strip: 18    Edep: 0.215085 MeV
layer: 2    sector: 5    strip: 220    Edep: 0.283442 MeV
layer: 3    sector: 8    strip: 190    Edep: 0.129059 MeV
layer: 3    sector: 8    strip: 191    Edep: 0.177371 MeV
layer: 4    sector: 8    strip: 13    Edep: 0.255779 MeV
layer: 5    sector: 10    strip: 17    Edep: 0.172112 MeV
layer: 6    sector: 10    strip: 170    Edep: 0.160031 MeV
layer: 7    sector: 14    strip: 58    Edep: 0.153398 MeV

Of course, to use this data it is much more likely we will
be organising more like:

layer   sector   strip   Edep
1          5            18      .21508
etc

In fact, this system is probably not directly suited for
simulated electronics output as we want to integrate
the energy deposited in a strip over a certain amount
of time, and then read that out. Right?
