Unpaired t-test on the beta file of session 1 vs session 2

[arnodelorme]

There are no variables, only the constant.
Upon doing an unpaired t-test to compare the constant for session 1 and 2, I get this error. I will try to see if I can share the STUDY.

Unrecognized function or variable 'tmp_data'.
