[caret-users] t-test iteration quits

[Donna Dierker]

This will happen every time, if you have only only four columns in 
EACHMETRIC.

It can only run a max of 2 to the k iterations, where k is the number of 
columns in the metric file -- could be subjects or sessions for a given 
subject.

If I give iteration fewer than 16, it runs fine, but anything above it, it quits at 16. I can't seem to find where this magic number 16 is coming from. Below is the command I'm running:
