-===== =====
+GLM takes a design matrix (DESIGNMTX) as input to perform a general linear model
+multiple regression analysis on the current 4-D image data set.
+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:
+  * 1 - generate a beta map for each column in the DESIGNMTX
+  * 2 - generate all beta maps together in a single 4-D output data set
+  * 4 - generate a residual 4-D data set (the original data with all DESIGNMTX waveforms regressed out)
+DESIGNMTX is the name of the design matrix, already loaded using the [[jvs:fscan:manual:chapter2:design|DESIGN]] or [[jvs:fscan:manual:chapter2:physio|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.
