Hi Yoon - It sounds like FSL's bedpostx postprocessing script failed. You can run it like this:
bedpostx_postproc.sh /path/to/your/subject/dmri
This script merges the results from all the slices. It's possible that something went wrong with the slices (you ran out disk space for example). If the slice results are ok, this'll do it.
Best, a.y

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
