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.
Although it's not built into 3dDeconvolve, you can use 3dZcutup to extract the dataset into slices or groups of slices before 3dDeconvolve. Then use 3dDeconvolve with the slice datasets. Then 3dZcat the results back together. A script doing a little more than this is included in this old thread where there had been a similar problem.
