I don't know, probably an open question. The change in resolution will
certainly affect results. Using the higher res (ie, not downsampling to
1mm) will likely give you the best result.

External Email - Use Caution
Good afternoon,
I have two sets of MRIs with different resolutions (0.9mm3 and 1mm3
isotropic). At the moment I ran the hippocampal segmentation on both
so I assume that the volume I obtained from 0.9mm3 was downsampled to
1mm3 after recon-all. I just read that recon-all allows us to keep the
resolution using the -cm flag, the question is would the volume I
obtain after rerun with -cm from 0.9mm3 scans be comparable with the
volume I obtained from the other set (the 1 mm3 scans) or is it better
to keep the downsampled ones?
Some subjects also have high-resolution T2 (0.4x0.4x2 mm3) scans,
would running the recon-all with -cm affect the T1+T2 segmentation
result as well?
Thank you very much.
Kind regards,
Jacob
