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 Gang,

Thanks for your reply.

Unfortunately the '3drefit ' command couldn't append the fico parameters in the header of the dataset. But I have another question with this approach. I used the following 3dLocalBistat to output the dataset with Pearson correlation,

3dLocalBistat -nbhd 'RHDD(6)' -stat pearson -mask MASK+orig -prefix OUT A+orig B+orig

Since the volume of the rhombic dodecahedron with radius of 6mm is 432mm3 and the voxel size of A+orig and B+orig is 1x1x1mm3, the number of voxel pairs used in correlation analysis at the edge of the mask will be <432. Using a universal number of voxel pairs to derive the p-values may have a problem.

Any suggestions?

Phoebe.
