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,

I'm dealing with subjects that tend to produce large, frequent movents in all planes. They also have very tiny heads.
So far, I have decided which datapoints were unusable based on visual inspection of each run and the output of 3dVolreg, and censored them while running 3dDeconvolve.

Getting rid of those datapoints (I mean, physically eliminating them from my bricks) would be a total nightmare and also methodologically incorrect, as I understand.

I was wondering though if it would be a good idea to replace the nightmarish subbricks with something like a non-offensive datapoint, or a mean image of some sort. The plugged-in images would still be ignored in Deconvolve. Do you see any advantages in following this procedure? How would I go about it?

thank you so much for your great work

cristina
