Depending on the FLAG option, the output may be a single data set or multiple data sets.
FLAG - specify processing options (combine options by adding values:
DESIGNMTX is the name of the design matrix, already loaded using the DESIGN or PHYSIO commands. If no valid matrix name is specified, the current active design matrix (most recently used in a DESIGN or PHYSIO command) will be used.
OUTNAME is the name prefix to use for all new data sets created by the GLM.
