Hi Martin

yes, 1.3mm is probably fine and even 1.5 might work. It is really an empircal question. We have done a ton of 1.3mm, so that response was overly conservative.

Hi FS experts, I came across this post https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2013-June/031245.html by Dr. Bruce Fischl, where it is mentioned that "You won't be able to analyze the data unless it is T1-weighted with voxels that are <1.3mm or so in any dimension."

However, I came across several papers in high impact journals, including papers published in Cerebral Cortex e.g. a very nice paper by Dr. Winkler https://academic.oup.com/cercor/article/28/2/738/4668693, other one is https://www.ncbi.nlm.nih.gov/pubmed/28183529,%C2%A0where the authors used voxels of size 1.3 mm or 1.33 mm.

Could you please comment on this contradiction whether voxels of this large size or even larger than 1.33 mm can give decent/correct results, or it is not advisable at all?

Thanks.
