External Email - Use Caution        

Thank you Tim!

Does someone from Freesurfer have any insight on this?

Best,

Shawn

Dear Shawn,

I can't fully answer your question, but maybe as a start:

I think the idea behind the suggestion to run recon-all on the template is that this would allow you to map the results of the FreeSurfer thickness analysis (which are in by default mapped to the fsaverage template if you run qcache) back to your template. I think you could even leave fsaverage out and map directly to it.

I have had a look at the NIFTI file you provided though (a preview image is attached to this email for others), and it looks like it is not a complete T1 image but a scull-stripped brain only. I think simply running recon-all on the file (you need nothing but a T1-weighted NIFTI file to run recon-all) will not work. You could start the recon-all pipeline at a later stage (after skull stripping), but maybe you should wait for another answer before proceeding any further.

Tim

I have seen a couple of posts on this, but am not clear about the process. For example, the response to a similar comment was to “run recon-all on the AAL anatomical T1w volume template”. At this point, I do not know what files, transformations, and/or code modifications are needed. For example, does the brainnectome template volume need to be preprocessed in any way, does it need to be saved in the MGH format? If so, how is this done? Does the process require any other files or subroutines?
