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

The answer to question 1 is no, at least for now. As the plugin currently works, the Draw Dataset plugin doesn't transform the atlas data to the space of the dataset (with the exception of transforming back to the orig/native space from a standard space). That's in contrast with the way whereami works, transforming coordinates when the transformations are available.

If you want to use an atlas from another space, you can either transform the dataset to match the space of the atlas, or, more likely, transform the atlas to match the space of the dataset. For MNI, TLRC and MNI_ANAT spaces, these transformations are all stored in AFNI in the AFNI_atlas_spaces.niml file and shown with whereami -show_xforms. There are a number of messageboard postings on how to go among TLRC/MNI/MNI_ANAT spaces, but let us know if you run into any problems.

The MNI_ANAT space is a shifted version of the MNI space. The spaces are described in the class materials here:
