ROOT DST Maker Instructions

Generating DST's from reconstructed LCIO files can be done by issuing the following command from a terminal: 

dst_maker LCIO_INPUT_FILE [additional input files] -o OUTPUT_FILE_NAME.root

This command will generate a DST with all GBL collections empty.  In order to run the GBL fitter and generate the GBL collections, the following command can be issued from a terminal:

dst_maker LCIO_INPUT_FILE [additional input files] -o OUTPUT_FILE_NAME.root -g -b B_FIELD

Note that when enabling the GBL collections, the magnetic field strength needs to be passed as a parameter to the DST maker.
