[MINC-users] mincreshape segfault and general behavior

At a guess I'd say this is a problem that I've seen surface a few
times with particular combinations of HDF, netCDF and MINC2.x when
working on MINC1 files. Are the input files MINC1 or MINC2? If MINC1,
you should be able to get around this by running mincconvert on them.

I take it you mean mincresample here?   If so then mincreshape does no
averaging or interpolating and mincresample does.
