Yes, that is correct. The “conform” step resamples to 1mm isotropic (among other things)

Subject: [Freesurfer] recon-all output resolution

Hi all,

Is the resolution of mri/*mgz files produced by `recon-all -all` always 1mm^3 regardless of the resolution of my input unless -hires is used?

This is what I found in recon-all.log:

without --hires:

mri_convert 001/mri/rawavg.mgz 001/mri/orig.mgz --conform

I believe the `--conform` flag does the resampling for all resolution.

with -hires:

mri_convert 434/mri/rawavg.mgz 434/mri/orig.mgz --conform_min

Best,
Tashrif
