Hi Anna - There was no method for intra-subject (diffusion to structural) registration selected in your config file, so some steps were skipped. Change the 0 to a 1 in this line: "set doregbbr = 0" and then rerun the preprocessing (you can skip the steps before the intra-subject registration if you want).

Best,

a.y

Dear all,

I am unable to get the dpath folder after the running the "trac-all path " step, although it shows an information on the terminal as "trac-paths finished without error".

Earlier, I had experienced an error with "trac-all bedp" but I ran it locally by directly using the "bedpostx <file path>" command. A dmri.bedpostX folder with all the files have been created . Following this, I encountered the above mentioned problem for pathway reconstruction. I have attached the config file and trac-all.log file.

Would appreciate any help.
