[MINC-users] mincresample and weird intensities

[minc-users@bic.mni.mcgill.ca]

Hi Andrew,

I have been using mincresample to change image resolutions as well.  I 
have found that you often need to specify the # of elements (-nelements) 
and origin (-start) as well.  Otherwise the resampled image may have an 
unusual size and location (i.e. one that exists in empty space and 
displaced from the object you would like to view).  Perhaps this is what 
is producing your error.  Good luck,
