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

Hi Robin,

Okay, I will test with the NL_warp option.

Regarding the anat resolution, it goes down to 2 mm^3 because you are using a 2 mm template, MNI_avg152T1+tlrc.

Importantly, that is a low-res blurry template, and as such, we would never recommend it for non-linear registration (or even affine, for that matter). NL-reg should use a fairly high-quality template. The current practice is to actually run @SSwarper (to align to the MNI152_2009_template_SSW.nii.gz template) for skull-stripping and standard space warping *before* running afni_proc.py. Then the output of that can be give to afni_proc.py via -tlrc_NL_warped_dsets. See example 6b:

afni_proc.py -show_example 'example 6b'

But anyway, I will run this with -tlrc_NL_warp and let you know how it goes.
