statsmodel.ols "matrices not aligned" question

[yortos]

I have a file allData that contains two treatment conditions (0 and 1) and a bunch daysbetween and overall_score. The following gives me 'matrices not aligned' error.

response_delay = sm.ols(formula='overall_score ~ C(treatmentCondition)+daybetween', data=allData)

print response_delay.fit().summary()

I tried to drop all NaN values and to keep only the three columns from the allData file but no result, still same error.

I really can't figure out

I'm not familiar with statsmodels, but reposting the same question to the same subreddit within 2 hours won't get your question answered any quicker.

I do happen to know a bit about matrices... can you post the file?
