[Freesurfer] Tracula question: trac-all config file and number of B0 specification

2011-06-10 Thread Deryk S. Beal, Ph.D.
the Tracula config file: *Step7.3: Specifying Number Of low-b Images* The last step to set up if not using original DICOMs would be to specify the number of low-b images with the following variable: set nb0 = *No. of low-b images* Thank you in advance for your help. Cheers, Deryk Deryk S. Beal

Hi Priti In addition, if I run bedpostx from the command line as follows: bedpostx /usr/local/freesurfer/subjects/C001/dmri it works just fine without errors. Deryk Deryk S. Beal, Ph.D., CCC-SLP, S-LP(C), Reg. CASLPO Speech-Language Pathologist C.I.H.R. Post Doctoral Research Fellow
