External Email - Use Caution
Hi. I am just getting my feet wet with running my subjects through the Freesurfer processing stream, so the following question night be a bit trivial (I hope):
I have run qvlSegmentHippocampal subfields on one of my subjects, and it completed just fine with what seem to be the appropriate outputs in the subject's mri folder. I have another 100 subjects to run, but want to make sure I can accomplish what I would like to on this subject first. The images which I see are sub-images, i.e. these have fewer voxels compared to the original image, but in the native T1 space resolution (= 1 mm3). I would now like to register the subfields in the native space (my DTI/NODDI maps are already registered into this space), to obtain mean values within each subfield. How can I transform these sub-field images back into the native T1 space, or is there a method within Freesurfer to perform the math (e.g. similar to fslmaths)?
Thanks,
Mark
