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.
I'm using 3dmaskave to calculate some statistics from hand-drawn ROIs. With the -drange option it is possible to exclude certain values, but because I have values that range from negative to positive, I'm not sure how to exclude only the zero values (reflecting signal dropout) while including all other negative and positive values.
