Hi Scott - Which version of FSL are you using? I cannot replicate this behavior of fslstats on our data.
Thanks, a.y

Hi, I have received the following error message (copied from trac-all.log file).

The file (dwi.nii.gz) exists in the correct location, and appears to have the correct number of frames (60 directions + 10 b0). We scan on a Siemens 3T tim trio. I unpack the data using unpacksdcmdir and I specify the resulting .mgz file in the tracula config file. Running locally on mac os 10.6.8.
Any suggestions would be appreciated. Thanks, Scott _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
