Solid output

== Location of package ==

• We are currently using the "banks" package that Maurizio built to convert evio format to root.
• The package can be aquired with: svn co https://clas12svn.jlab.org/repos/trunk/clas12/banks

== How to run it ==

• Set the appropriate enviroment with: setenv JLAB_ROOT /site/12gev_phys and source $JLAB_ROOT/ce/jlab.csh
• Compile the package with: scons

The executables are located in the bin directory

== What can the current version do for you? ==

There are four executables in the bin directory and I will exemplify what they do using a evio output file that Zhiwen produced with SoLID GEMC:

• banks_example1: this needs as argument the name of the database and lists on the screen the banks

./bin/banks_example1 clas12_banks

Loading bank definitions from clas12_banks

Bank <BMT> loaded with id 460

Bank <BST> loaded with id 400

...

• banks_example2: this needs as arguments the evio file name and the bank name and will print on the screen all the variables from the bank specified.

./bin/banks_example2 output.ev FLUX

...

ETot: 31.9338 31.4093 0 1.41605 0 0.482844 3.49607 1.08118 0 1.50174 ...

<x>: 720.504 1223.97 1289.92 1243.55 1289.86 1214.5 1204.92 ...

...

• banks_example3: this needs as arguments the evio file name, the bank name and the variable name and it will print only the variable specified at the command line.

./bin/banks_example3 output.ev FLUX ETot

...

>> Event number: 10

FLUX, ETot: 31.9338 31.4093 0 1.41605 0 0.482844 3.49607 ...

...

• banks_example4: this will convert the evio file to root and it needs as arguments the evio file name and the bank name

./bin/banks_example4 output.ev FLUX

I used it to convert the evio file that Zhiwen sent me and it worked fine. Below I attach 2 picures that I got from the root file:

total energy deposited from SoLID GEMC root output file

number of events from SoLID GEMC root output file

== Room for improvement ==

Currently the program that converts evio to root needs to have put in by hand the bank variables that the user wants in the root Tree. Ideally, conversion program should be smart enough to avoid that.
