mask_values

mask values in a volume based on a range in another volume

mask_values input1.mnc input2.mnc output.mnc min1 max1 set2

DESCRIPTION

mask_values masks values in the second volume based on a value range in the first volume. For each voxel, if the value in input1.mnc falls within the range (min1, max1), the corresponding voxel in the output is taken from input2.mnc. Otherwise, the voxel in the output is set to set2.

This is useful for selectively extracting values from one volume using another volume as a mask, with control over the acceptance range and the replacement value for rejected voxels.

EXAMPLES

mask_values classification.mnc t1.mnc masked.mnc 2.5 3.5 0
