The problem is that line

https://github.com/UIUCSinhaLab/GEMSTAT/blob/master/src/seq2expr.cpp#L331
( Update: now https://github.com/UIUCSinhaLab/GEMSTAT/blob/master/src/seq2expr.cpp#L340 )

needs to change the "false" to "true".

Needs to be fixed on both main branches.

Definitely my fault.

The code should be fine now, can we close this?

Not until we have a regression test to test it?
