[Freesurfer] Tracula - error in pre-proc

Hi,

I do the pre-processing with the following command:

trac-all -prep -c ./scripts/dmrirc_single_subject

THe process exits with error when it comes to fslroi (attached pls find the log file). I try to re-run the fslroi command as follow:

fslroi /autofs/space/guasha_001/users/phoebe/strab_func_chan4/strab_func_chan_diffrecons/040826_cst/dmri/dwi.nii. gz /autofs/space/guasha_001/users/phoebe/strab_func_chan4/strab_func_chan_diffrecons/040826_cst/dmri/lowb.nii.gz

0 25

It works and the lowb.nii.gz looks normal. In case if I have the same problem with another dataset, how can I incorporate the number of frames (25) in the trac-all command for the fslroi? Can I continue the remaining procedures of trac-all from this point?

Thank you.

Phoebe.
