Re: [HCP-Users] Processing Diffusion MRI Data

[Glasser, Matthew]

Why do you need to use FLIRT/FNIRT with already registered data?  As for the others and aside from the flags you already mention, I think the recommendation for bedpostX will include these flags: -n 3 (for 3 fibers)  --cnonlinear --rician --model=3 Not all of this may yet be available in the public release (you might need to use --model=2 for now).

Is there some documentation that I could look at that outlines how to use bedpostx, FLIRT/FNIRT, DTIFIT and probtrackx with this data?   From what I’ve found in the archives, I need to do the following:   Bedpostx:  include the –g option FLIRT/FNIRT:  do I include any extra options here? DTIFIT:  include the –gradnonlin option   Is this all that needs to be done to have this data ready for tractography? Or are there steps that I have missed?   Please let me know if there is any documentation I have failed to locate.    Thanks, Derek Archer       _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users   The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
