Hi Anastasia,
That did the trick! Thanks so much!

Hi Jared - We haven't reproduced this error on our end. So if I understand it correctly, replacing "bedpostx_seychelles" with "bedpostx" in trac-all would solve the problem?

Hi Anatasia,
Thank you for the response.
I've reformatted the files and -prep ran fine.
I'm receiving a similar error to some other users upon running -bedp
Where bedpostx fails immediately
I wanted to point out, and wonder if other folks have had any luck, that if I try running bedpostx from FSL directly on the dmri folder, it starts normally. I can then kill the bedpostx process, and relaunch trac-all -bedp -c ... and things seem to be continuing...
It still returns the "unexpected operator" errors that other users have reported but it does not break to a command prompt anymore, and instead beings return the "0 slices processed" ... iterating message.
I'm curious, has anyone else had luck navigating around this bedpostx error? Or would it be best to just run bedpostx separately in FSL and return to trac-all after the bedpostx processing is complete?
Thanks again! Jared

Hi Jared - Have you looked at $FREESURFER_HOME/bin/dmrirc.example? You can specify bvecfile, bvalfile, and nb0. Currently these are assumed to be the same for all subjects. The format is 3 columns for bvecs, single column for bvals. Otherwise you shouldn't have to do anything else to them (hopefully! :)

Hi Freesurfer experts, I was wondering if you all had some advice for getting trac-all up and running. I'm trying to work up a trac-all configuration file for a group of subjects, previously processed in FSL. We extracted the Siemens bvec and bval files for the FSL pipeline when importing the dicoms through dicom2nii. I know FSL bval and bvec files are organized in a different matrix shape from what Trac-all wants. Has anyone had sucess with transforming these files? Should/do I need to worry about whether to flip the orientation on bvec files as the images seem to get flipped in the early steps of Trac-all? Also is it possible to feed the configuration file a list of bvec files (for each subject) similar to how we feed it the dicom directory for each subject, or should I create a configuration script for each subject pointing to their bvec file specifically. Thanks in advance for help! Cheers, Jared
