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

Hi again!

Thank you so much for the feedback!

The version I was using was indeed old. I must say the latest one is quite cool! I really like the QC ouput and the overlaying function in the GUI!
The 'nmi' cost function did wonders, cheers! I also switched to the second echo as a ref echo as it has much more signal (even though the contrast is tiny bit poorer).

I've pre-processed our entire dataset and the few scans I've checked so far are looking really nice!
There are a few things that are puzzling me though (sorry for getting a bit off-topic):
  1. I'm curious as to why the QC html file doesn't get generated for some of the sessions (see part of the ouput bellow).
  2. Looking at the Degree of Freedom part, it got me wondering... What is an 'acceptable' post-(?!)pre-processing DoF value?
  3. Given the substantial signal loss that is plaguing our data, I wanted to ask you what would be a good way of creating a mask that would include only voxels that have signal. Not sure how to approach this as there are some differences in the extent of signal loss in the different participant sessions.

Thank you!!!
Misho
