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

As I recall, Ziad used the volume rendering plugin to decide what a good threshold for each subject was -- I think he was about the first user of this plugin, in fact. The -1clip xx option is the 3dmerge function to use for this thresholding, once you've figured out what 'xx' should be; the clustering option you described is the correct way to cluster with 3dmerge.

You can interactively use the new rendering plugin to set a threshold and clusterize, if the angio dataset is loaded as the Overlay, and use the "Show Thru" mode to have the above-threshold voxels shine through the brain.
