Hi Kiely - It's strange that bepostx would create ph2samples and not ph1samples. These are the orientation angles for the 2 anisotropic compartments, so if there's a 2nd there should be a 1st. Have you asked about it on the FSL list?

Hi Everyone --
I've been having difficulty getting Tracula to run smoothly on our cluster. Similar to others on the listserv, the bedpost step was not creating the necessary files causing an error during the -path step. Based on previous posts, I ran bedpostx on the dmri directory. This initially seemed to work (I no longer received the message "1 slice processed" over and over), but for some reason the merged_ph1samples.nii.gz file is still not being created and I continue to run into an error when I run -path. It does create a merged_ph2samples.nii.gz output file.
Any help would be greatly appreciated.
Thanks,
Kiely
