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.
Some of the programs internally 'binarize' the data before Dice calc, and others don't. So, for pure "Dice" calcs, you would be safest make strictly binary masks for comparison. For example, @DiceMetric will recognize separate ROIs by different integer values in a dset and try to calc Dice values between 1s in each dset, separately from the 2s in each dset, etc.
