was wondering if anyone have experience with freesurfer segmentation of the hippocampus in SPHARM.
I tried various tricks but the registration really does not work. It is obvious that there are several irregularities of the shape from FS but I find it a bit strange that I cannot get the registration to work … as the overall shape is relatively similar between subjects.
So far i tried to increase or decreas spherical complexity 10 - 15 - 20 - did not work for any of these.
I also tried to use different subjects as reference for the registration (choosing one that seem to have a relatively regular shape).
Is there anything else that I can try?
