fScan Reference Manual, Chapter 2 (CmdLineOptions:Expr): Viewmask
Viewmask -- Use 1 image to mask multiple slices in any 3D view
usage: -expr viewmask RefImage viewplane [maskthresh flag slice0 nslices]
VIEWMASK applies a single mask image (REFIMAGE) to mask voxel values in multiple image planes along any axis (X,Y,Z).
The axis is specified by the VIEWPLANE argument as:
- 0 - default Z axis
- 1 - coronal
- 2 - sagittal
- 3 - axial
The REFIMAGE must have the same XY dimensions as the active data set in the selected VIEWPLANE.
MASKTHRESH can be used to specify the minimum “ON” value in REFIMAGE; the default is 1 (any nonzero value).
FLAG:
- 0 - default; set values to zero where REFIMAGE is less than MASKTHRESH
- 1 - invert the mask; keep values where REFIMAGE is greater than or equal to MASKTHRESH
SLICE0 and NSLICES can be used to apply the mask to only a subset of slices along the VIEWPLANE axis (default is all slices).
