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

These changes are in the AFNI source code (afni_src.tgz) now and will be compiled up into the binaries by tomorrow morning (Tuesday 17 June 2014).
  1. From within the Clusterize Report page, you can now save a dataset with a mask from a single cluster. To do this, you must use the right-click popup menu attached to the very top of the Report page (where it starts with "Voxels survived"). The second item is labeled 'Save->Mask??' -- this is a toggle switch. Click it to the on state, and all the cluster-specific Save buttons will change to be labeled Mask. In this state, pressing the Mask button for cluster #3 (e.g.) will save a dataset with the mask for that cluster. Turning the 'Save->Mask??' toggle off will restore these buttons to their 'Save' label and functionality.
  2. SAVE_UNDERLAY and SAVE_OVERLAY commands have been added to the AFNI driver repertoire. Thus, you can use the INSTACORR command to create a single-subject seed-based correlation volume and then a command like SAVE_OVERLAY Fred to save it to a dataset (with prefix "Fred"). The file README.driver explains what little more you need to know.
  3. The dataset range label in Define Overlay now has a popup hint that shows the range of the selected OLay volume as thresholded. This can be helpful for selecting the display range in the controls just underneath this label.
  4. If you set the environment variable AFNI_PBAR_FULLRANGE to YES in your .afnirc file, then the selected overlay colorization range will show next to the color scale "pbar". This is a convenience to help in explicating the dataset-numbers-to-colors process. At some point this feature will become the default, but at the moment I'm waiting to see if any more bugs show up. It was causing crashes last week, and although I fixed that problem, something else may crop up. (The colorization process code goes back to 1994, and some of it hasn't been touched since then.)
