BUG: wrong time point @sjfahr
I added a third metric to monitor Dice (Straight-up Dice, not the 1-Dice). Then I modified the *.in files to include it (but it has a weight of 0).
Added a fourth metric. Here are the metrics:
1) L2norm
2) 1 / (dice + 1E-7)
3) dice
4) 1-dice

The *.in files weight metrics 1 and 2 equally. 3 and 4 are 0 and kept for posterity.
