Dear Freesurfer experts,
I am currently planning a study in which I want to investigate changes in gray matter due to training on structural MR images. I heard some rumors that although FreeSurfer can of course process images with different voxel sizes, it always somehow "transforms" the voxel size to 1 x 1 x 1, irrespective of the originally obtained image resolution. I've been wondering if something has changed in this regard, that is, whether FreeSurfer is now capable of maintaining a higher resolution (eg, 0.8 mm) throughout all the analysis steps? As I am looking for very very tiny changes I would like to acquire images with 0.8mm resolution. But if FreeSurfer has to convert these images with the help of some estimation processes at some point of the reconstruction, I would rather like to acquire 1 x 1 x 1 images in the first place.
Thank you so much for your help!
All the best, Elisabeth
