[MINC-users] mincresample changes voxel values

[Jason Lerch]

Quick word of caution: are you reading these values using Display or 
register? They do their own internal conversion - to make sure this 
problem is really a problem, try binarizing a label (use mincmath 
-const2 35.5 36.5 -seg labels.mnc one-label.mnc) and then loading it in 
some viewing program.

Hope this helps - if not, see if the command resample_labels gives you 
more satisfaction.
