Hi Anastasia,

trac-all -prep completed without error.

I thought trac-all -bedp starts and ends without any error but trac-all path failed with these messages.

Loading BEDPOST parameter samples from */dmri.bedpostX

niiRead(): error opening file*/dmri.bedpostX/merged_ph1samples.nii.gz

ERROR: Could not read */dmri.bedpostX/merged_ph1samples.nii.gz

I looked at the dmri.bedpostX directory and all slices exist in the dmri.bedpostX/diff_slices directory but realized the trac-all -bedp phase did not create the

merged samples in this directory.

I am currently runnning with

FSL/5.0.6

Program versions:

$Id: trac-all,v 1.56 2014/05/26 08:28:32 ayendiki Exp $

and freesurfer version 5.3

I looked through the mailing list to see if someone ran into a similar problem but could not find a good solution. Do you have what may have caused this? Any other files I would like to look into?

Thank you

Yoon
