What does NonRevP_learn_corr_fed.txt look like? If
every regressor has a duration attached, that would be
with the intention of using dmBLOCK or dmUBLOCK
for all of them.
If all of the durations are the same for some stim timing
file, it is not necessary to include them. But if you have,
then perhaps dmBLOCK or dmUBLOCK should be used
for all stim classes.
