[MINC-users] resource for source_mask option in minctracc?

[Andrew Janke]

Jonathan, 

This option allows you to specify a minc file as a mask to use during
the fitting. ie:

   minctracc ....  -source_mask mask.mnc .....  

It has the effect that the similarity function is only evaluated
within the mask as applied to the input source volume.

This means: 

   * Fitting is often faster  (less voxels to compute obj function over)
   * Fitting is more precise for the area within the mask as features
       from structures outside the mask are ignored.
