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

All the spatially transforming programs remove the obliquity of the data, but maybe that one shouldn't, or should only match the grid and obliquity of the base dataset. In any case, to restore the oblique information, you can do something like this:

3drefit -atrcopy IJK_TO_DICOM_REAL original_dset warped_dset

To use this, the grid has to be exactly the same size, i.e. the number of rows, columns and slices are the same for both the warp and original datasets.
