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

Thanks for you suggestions.

Should I be concerned about including outliers in my calculation of the mean signal?

If so, how do you recommend that I address this?

(I am not using the first 4 images of the scan--for either the 3dDeconvolve analysis or the normalization), but am concerned that other outliers in the dataset will skew the calculation of the mean.

Thanks--
Jane Lange
