3 # So to get the list of input files. One must call :
4 # search(), to get the list of primary files
5 # search2(), to get the list of eventual secondary files
6 #
7 # The selection of files is configured thanks to shell
8 # environment variables:
9 #
10 # DD_RELEASE, for example CMSSW_2_2_0_pre1
11 # DD_SAMPLE, for example RelValSingleElectronPt35
12 # DD_RUN, for example ''
13 # DD_COND , for example MC_31X_V2-v1
14 # DD_TIER , for example RECO
15 # DD_TIER_SECONDARY, for eventual secondary files
16 #
17 # DD_SOURCE:
18 # das: use das
19 # dbs: use dbs search
20 # lsf: use dbs lsf
21 # /castor/cern.ch/cms/...: assumed to be the path of a castor directory containing the input data files
22 # for relvals: '/castor/cern.ch/cms/store/relval/${DD_RELEASE}/${DD_SAMPLE}/${DD_TIER}/${DD_COND}/'
23 # for harvested dqm: '/castor/cern.ch/cms/store/unmerged/dqm/${DD_SAMPLE}-${DD_RELEASE}-${DD_COND}-DQM-DQMHarvest-OfflineDQM'
24 # /eos/cms/...: assumed to be the path of a castor directory containing the input data files
25 # for relvals: '/eos/cms/store/relval/${DD_RELEASE}/${DD_SAMPLE}/${DD_TIER}/${DD_COND}/'
26 # for harvested dqm: '/eos/cms/store/unmerged/dqm/${DD_SAMPLE}-${DD_RELEASE}-${DD_COND}-DQM-DQMHarvest-OfflineDQM'
27 # /...: assumed to be the path of a text file containing the list of input data files
28 #
29 # All except DD_SOURCE can use wildcard *.
