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 Rick,

I found the following article that seems to indicate what you suggest:

[www.ncbi.nlm.nih.gov]

I assume 3dDeconvolve implements an adaptive two-stage FDR approach as it is described in 3dFDR. According to the paper, would this mean that a two-stage FDR approach might not be appropriate if statistical values are very high in the entire brain?

Dataset was acquired at 7T and preprocessed as follows:
- RETROICOR, RVT, CR, and Legendre polynomials up to 4-th order
- Smoothing with 4mm FWHM Gaussian kernel
- Computation of signal percentage with 3dcalc -expr 'a - mean(a)/mean(a)'

Yes, please let me know how to upload the data.
