Dear FreeSurfer Developers:

I am attempting to perform cluster-wise correction for the along-tract measures, as described on the Tract statistics tutorial (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TraculaStatistics). But, when I run the command below, the flag --1d is not recognized.

Command: mri_glmfit-sim --glmdir cc.bodyp.FA_Avg.glmdir --1d --cwp .05 --perm 1000 1.3 pos
Error: Flag --1d unrecognized.

I could not find similar errors reported. Does anyone have any thoughts on how to trouble-shoot this? The FreeSurfer version I'm using is 7.2.0 on an M1 Mac machine with macOS 12.1. Thank you so much for your help.

Sincerely,

Taka
