Getting the analysis software
Minimal CLAS software for EG1 analysis
download files from the JLAB CVS repository using the command
type the command below in order to tell CVS to use ssh
setenv CVS_RSH ssh
if you have an account on the JLAB computers you can do
cvs -td :ext:USERNAME@cvs.jlab.org:/group/clas/clas_cvs co packages
where USERNAME is your JLab username
I will get all packages for convenience but in the end I will remove some
subdirectories which the EG1 dst reader doesn't need.
I only kept the following subdirectories under the "packages" subdirectory.
bankdefs
bos
bosbank
bosio
c_bos_io
cc
c_cern
clasbos
clasutil
cms
c_sql
CVS
fdump
fpack
fputil
include
Makefile
rtm
utilities
EG1 DST reader
The EG1 dsts reader is used to uncompress the EG1 DST data files for analysis. The DST library has at least 3 version now so you must use the correct DST library with your data file.
UNIX software
apt-get install paw apt-get install paw++ apt-get install xemacs
Getting Data files from JLAB
downloading to offsite place
running on JLAB farm
