AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

I'm sorry, I don't yet understand much of the MRI (and file extension) terminology.
The GRADS.dat file is 3 columns by 288 rows.
The HCP data comes from scans with 95,96,97 gradients (=288).

So, I think I'm getting this now, my last question being: for the 1dDW_Grad_o_Mat, do I truncate my bvals to
bvals[1..287]
bvals[1..288]
bvals[0..286]
bvals[0..287]

I'm assuming bvals[1..288], to remove the first gradient (B=0) and capture the remaining 287?
Thanks again for your time! Hopefully I can proceed on my own from here on in!
