[[what-you-need]]
= What you need:
ROOT 5.34/35+ gcc compiler (general)
[[source-codes]]
= Source codes:
Located in *src* directory...
*TDISMC_EIC.cpp* : pion structure function with ep scattering at JLEIC
*TDISMC_EICn.cpp* : pion structure function with eD scattering at JLEIC
*TDISMC_EICK.cpp* : kaon structure function with ep scattering at JLEIC
*cteq/* : cteqpdf.h and data based call files (c++ wrapper) *cteq-tbls/*
: nucleon PDFs table *structure_functions/* : various regularization
form for pion SF/FF
[[how-to-change-inputs]]
= How to change inputs:
Located in *inputs* directory...
*kinematics.inputs* : edit this document to change simulation kinematics
(e.g. number of events, x range, Q2 range, pbeam, kbeam)
All other constants are changed in *src/TDISMC_EIC.h*

[[root-and-lund-outputs]]
= ROOT and LUND outputs:
In the *OUTPUTS* directory are the ROOT and LUND outputs for the
simulation for further analysis.
[[running-geant4]]
= Running GEANT4
Located in *g4e_files/* directory...
*./run_g4e.sh* : Will run the python script for the GEANT4 simulation
from the TDIS_lund.dat file *eic_g4e.py* : This python script will run
GEANT4 simulation for the lund file specified for detector='jleic' and
beamline='erhic'
