Hi Valentin
we do reslice it for the basic processing, but you can do post-hoc
surface deformation and things like hippocampal subfield segmentation at
the native resolution. Or you can use the -cm switch to prevent the
reslicing, but it is something we don't have a ton of experience with.

Hi,
we are currently using Freesurfer for a complete segmentation of 7T MRI
Datasets with isotropic voxels of 0,7 mm. Now the question has come up
whether Freesurfer calculates with this original submilimeter resolution or
if it internally reslices our data (e.g. to 1mm), which could result in a
loss of quality. If so, is it possible to change Freesurfers settings to
obtain optimal results from the segmentation?
Any help would be greatly appreciated,
best regards, Valentin Frank
