Such an error might occur if /models/mca-dura.both-lh..nstd21.fhs.h5 is not a valid hdf5 file, or /models is a mount point or soft link in your computers file system. It does however look like some previous code was able to open /models/mca-dura.both-lh.nstd21.fhs.h5 and load in the weights.

You could try cd’ing to /usr/local/freesurfer/8.1.0/python/lib/python3.8/site-packages and see if you can read the file, i.e., “cat /models/mca-dura.both-lh.nstd21.fhs.h5”. I would at least try re-locating that model file to be under a known path where you always have read/write permission like your home directory.

- R.
