Which version of mincconcat are you running?  And if it is MINC 2 is
the file netcdf or HDF?

One of the primary reasons for the shift to MINC2 (and thus HDF5) was
to get around the size limitations of netcdf. If you are using large
volumes be sure to either use '-2' when you originally create all your
data in MINC (and then it will flow on) or to be sure set this env
variable:

   export MINC_FORCE_V2=1

you can check on your file types using "file".

ie:

gordon:map$ file /tmp/foo/*.mnc
/tmp/foo/green.mnc:                   Hierarchical Data Format (version 5) data
/tmp/foo/out.mnc:                     NetCDF Data Format data
/tmp/foo/trans.mnc:                   NetCDF Data Format data

You can convert a netcdf MINC file to HDF very easily using the following:

   $ mincconvert -2 in.mnc out.mnc
