minccmp range values

[andrewjanke]

Allow users to input a list of range/floor/ceil values.

Currently the range only applies to the first input volume.

Code for doing this is already in mincstats so copying that over should be straight forward.

So minccmp would completely ignore voxels outside the range, for every file? This seems to imply a sort of "and" operation, where the logic would be that we ignore any voxel that falls outside the prescribed range for any of the input volumes?

This feature request was prompted by Paul's request on minc-users for a different range/float/ceil for two input volumes. If we take the more general approach as per in mincstats then yes what you are suggesting makes sense:

if (a list of range/ceil/floor values is given){
   if (list size doesn't match the input files){
      bomb;
      }

   use them;
   }

else{  # only one value given
   set all values in the list to the input value;  # achieves logical 'and'
   }
