Hi-

Just a follow-up note to Daniel's post:

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.
