I keep running into the following error (see below) when selxavg3-sess gets to my third subject. I am assuming this is because this subject does not have all of the conditions modeled (that is, this particular subject does not have any incorrect responses). Is there a way to model an empty condition to get around this? I want a general contrast of Incorrect > Correct, but some subjects do not make any errors and therefore would not have this condition in their paradigm files.
Any advice would be greatly appreciated.
