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

3dresample and 3dfractionize have two approaches to doing this. The first interpolates the mask onto the output grid using different interpolation schemes. For masks, you will want to use the NN (nearest-neighbor) method. 3dfractionize allows a little more flexibility by allowing the resampling to include voxels that aren't partially filled or filled with different regions. One can pick the fraction to preserve the original value. See the help for each of these program or the afni11_roi.pdf class documentation for more details.
