Hi Cristian
it's not so much the difference in voxel size as it is the thickness and
anisotropy of your FLAIR voxels. You would be much better off getting 1mm
iso which would have comparable SNR to what you have now. You can try it,
but the 3.5mm slice thickness will probably mess stuff up
sorry

Dear Freesurfer experts,
I want to improve pial reconstruction by using FLAIR images in the pial
reconstruction (freesurfer v6.0).
Ø recon-all -subject subjectname -FLAIR /path/to/FLAIR_volume -FLAIRpial
-autorecon3
T1 was acquired in a 3T Phillips scanner with a isometric voxel size of 1
mm3, whereas FLAIR images have a voxel size of 0.5 x 0.5 x 3.5 mm.
Is there any issue in using different voxel sizes?
Thank you
