Dear FS experts,

I’m attempting to run dt_recon on my own DWI DICOM file with registration to corresponding structural data, as described in FS diffusion tutorial (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/DiffusionV6.0) I’m using FS version freesurfer-darwin-macOS-7.1.1-20200811-8b40551 on Mac (MacOS Big Sur  v. 11.1). I’ve already succesfully run recon-all on the T1 scan. However, when I’m running the dt_recon, I’m getting the following error:

Command I’m using: dt_recon --i $TUTORIAL_DIR/$subj/orig/DTI/S142783/NIFD_1_S_0001_MR_dti_WIP_b2000_64dir__br_raw_20120306104435815_50_S142783_I288323.dcm --s $subj --o $TUTORIAL_DIR/$subj/dtrecon

ERROR: dimension mismatch between y and X.
  y has 65 inputs, X has 66 rows.

I’ve searched the archive, however not finding any similar issues. Does anyone have an idea how to solve this error? Attached is the dt_recon.log.

Best,
Antti Cajanus
