That it is.  Get to http://packages.bic.mni.mcill.ca/ as fast as you can... ;)

We have striven to make MINC2 100% compatible with MINC1 so your
volume_io programs will work just fine against minc2.   (just change
to -lminc2 -lvolume_io2 -lnetcdf -lhdf5 -lm)

Jason has written some very nice MINC2 API tutorials here:
