Hello, I successfully ran trac-all -bedp, and when I run the next step I get the following error:
Loading BEDPOST parameter samples from /raid2/fmri8/study/volumetric/freesurfer/control/subject/dmri.bedpostX niiRead(): error opening file /raid2/fmri8/study/volumetric/freesurfer/control/subject/dmri.bedpostX/merged_ph1samples.nii.gz ERROR: Could not read /raid2/fmri8/study/volumetric/freesurfer/control/subject/dmri.bedpostX/merged_ph1samples.nii.gz Linux occipital.tch.harvard.edu 2.6.18-308.1.1.el5 #1 SMP Wed Mar 7 04:16:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

Word too long. ------------------------------------------------------------------------
Indeed, the "merged" file doesn't exist. I am running Freesurfer 5.1.0 and FSL 4.1.9. Here's what's in the dmri.bedpostX directory:
