simtb_createmask

PURPOSE

simtb_createmask() - Creates data mask with ones inside the head and zeros outside.

SYNOPSIS

function MASK = simtb_createmask(sP, saveMASKasNIFTI)

DESCRIPTION

 simtb_createmask()  - Creates data mask with ones inside the head and zeros outside.
                Note that this utility should NOT be used to determine
                a mask if motion is simulated since the head boundaries will move.

 Usage:
  >> MASK = simtb_createmask(sP, saveMASKasNIFTI);

 INPUTS:
 sP               = simulation parameter structure
 saveMASKasNIFTI  = FLAG to save MASK as a NIFTI file
 
 OUTPUTS:
 MASK             = MASK of ones where data are defined and zero elsewhere
