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

An update to the post above:

I have found the command 1dBport, which does exactly this. However, it always seems to output sine/cosine regressors of one timepoint less than the number of volumes. Is there a way to make it match the number of volumes so I can perform a regression, or am I misinterpreting how to use these regressors?
Would it be appropriate to increase the number of volumes by 1 to output my intended regressor length, or will this slightly frequency shift the band power of my intended bandpass?

Thank you in advance!
Will
