Hi Erik,

there’s no FreeSurfer program to do this in a straightforward manner. But you can:

1. read in the hippocampal subfield segmentation into matlab with the MRIread function in the $FREESURFER_HOME/matlab directory. 2. extract the major axis with the hippocampus using PCA. 3. Subdivide the subfields along that axis

You can find code to do 2 and 3 here: https://github.com/garikoitz/hippovol

Cheers,

Dear FS experts. I want to divid the FS subfield segementation into a anterior part, one middle part and posterior segment - or potentially divide the rang into 10% of the whole rang - and then move backword until I extracted 10 subparts.

Is there some way I can do that?
