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

Hey Gang,

> why did you need to convolve your seed time series since it's BOLD signal already?

When you ask why did we convolve, do you mean why did we perform 3dTfitter? If yes, we performed this step because 1) the SEED time series is generated by applying the mask to raw data that hasn't been convolved; 2) We need to apply the gammaHR with the increased temporal resolution to the upsampled SEED region files.

> I don't see any reason/need to have the following lines (are they 0's and 1's in FeAware.txt?):
> waver -dt 0.25 -GAM -gamb 8.6 -gamc 0.547 -gamd 0 -peak 1 -numout 1548 -input FeAware.txt'{0..1547}' > 1028r1.FeAware.1D

The FeAware.txt is just 0s and 1s. We performed this step to break the FeAware.txt up into the 6 runs.

What do you think? Thanks
Steve
