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.
I think the aptly-named and easy-to-find "waver" function can be used with -GAM and a few other options.
But the help text by Mr. Afni himself recommends using 3dDeconvolve instead somehow.
Since you are also an expert in Python, you may find scipy.ndimage.convolve1d() equally easy to use?
