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 guys:

To follow up on this - I read in a post on another forum that generally the raw physiological data should be used as input to a variety of software. If this is the case for RetroTS, my cardiac and respiratory data have different sampling rates (PPG: 10ms, RESP: 40ms). If I'm just inputting the raw data should I:
1) Downsample the PPG
2) Upsample the RESP
3) Run RetroRS separately for each measure with the raw data from each?

Also GE tacks on an additional 30s of data from before the start of the scan. I'm assuming this should be discarded before the processing?

Thanks for your help.
Lauren
