Reading in all files using simple pattern matching

To read in all files using a simple pattern matching use the following two lines:

import glob
EventSelector.InputCollections = glob.glob("/path/to/directory/InDetESD*.root")

Reading in all files on castor in a given directory

Reading in all files in a given castor directory is also not too difficult:

castordir = "/castor/cern.ch/path/to/files/"
collection = []
filelist = os.popen("rfdir "+castordir).readlines()
for i in filelist:
  collection.append("castor:"+castordir+string.split(i)[8])
EventSelector.InputCollections = collection
