Accessing data files

FTS copies the data files from the DAQ machines to

/pnfs/nova/rawdata/{TestBeam,TestBeam-Beamline}

The metadata is saved in SAM by the process which catalogs the files. Example beamline metadata (from the last beamline data file taken before shutdown 2019):

>> samweb get-metadata novabeamline_r003029_0001.root
