Hi Peggy - Yes, this error has been encountered before, and it should be
fixed in the latest tracula update. Can you please try it with this
version?

Hi,
I'm processing 3T data with 60 direction vectors and 2 images with b-val = 0.
Trac-all -prep has been failing at the command:
> mri_convert --frame 0 31 <my_subj>/dmri/dwi.nii.gz <my_subj>/dmri/lowb.nii.gz

Since --frame seems to only want one value, but we have 2 images with low b
values. Has anyone encountered this problem before?
