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.
The default warped dataset grid dimension is 1 mm. However, for the usual EPI time series data, this is too much resolution. The original data is usually at 3-4 mm resolution, so there is no reason to warp it to a 1 mm grid -- warp it to a 2 mm grid and the datasets will be 1/8 the size of the 1 mm grid.
