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.
Based on what I could find at sites like the link below, I believe those fields are in the format hhmmss.ffffff (hours,minutes,seconds,fractional seconds). The acquisition time would then be at 4:15 PM (16:15 in 24-hr time), 38.3125 seconds.
