Hi Alfonso and Conn users/experts/fans,

1) I am trying to import conditions for a gPPI from a csv file but get the following error:

Error using conn_importcondition (line 199)
multiple rows for condition Correct_Go subject 1 session 1

I am working on a Go-NoGo task with one session, four conditions: Correct_Go / Correct_NoGo / Failed_Go / Failed_NoGo. The onsets differ from subject to subject because mistakes are included in the conditions (Failed_Go for omission errors and Failed_NoGo commission errors).

I attached an example of the csv file for three participants. I feel like I did follow the accepted format for Conn so I am confused about this error message.

Could you please help with that?

2) Just anticipating a potential following issue, not all participants have the same number of conditions since some did not make any mistake and therefore don't have instances of Failed_Go and/or Failed_NoGo. Will this be a problem?

Many thanks in advance,
Arthur Montalto
