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

Thank you Daniel!

Just to make sure:

1. So it SHOULD work to remove the "-tlrc_opts_at -init_xform CENTER" option and to run @Align_Centers insead for the linear warping as well?

2. For the non-linear warping I should run @Align_Centers. Should I use the template as the base or the functional data?

@Align_Centers -base ~/abin/TT_N27+trlc. -dset T1+orig -cm
or
@Align_Centers -base fmri+orig. -dset T1+orig -cm

Beacuse neither of these methods work for neither for affine nor non-linear warping. I still get the cropping (for affine) and memory corruption (non-linear) problems. I think this is because I'm not solving the centerign issue. Even with the commands above I still get the "datasets are 70 mm apart" warning. So, what am I screwing up with the commands above? @Align_Centers does give me a set of base, dset and delta displace values (higher when using TT_N27 than the functional as base) so it seems that it finds the offset atleast.

The only way I can make this run (so far) is to only do the standard linear warping in combination with the "-tlrc_opts_at -init_xform CENTER" option.
