Thank you, you are correct, I figured that my analysis was actually using a subset of the runs which doesn't contain all 69 conditions. I would still like to use this subset of runs so I think I will make new para files that assign less conditions (some conditions are stimuli of similar types that

Within a given session you must have all conditions represented. They all do not need to be in the same run, but they must all appear at least once across all runs. It looks like only 33 of the 69 are there. BTW, 69 is probably not a realistic number of conditions, way too big. doug Gabriel A.

Hello, I have event related data with 69 different conditions, and every condition does not appear in every run. This causes selxavg-sess to throw an error. Part of the relevant debug output is below. Why does every condition need to appear in every run? Thank you, Gabe echo "$sess " | & tee

Hi Brendan, do you really need the full simulation? If you can use the mc-z, then we have a new version of the simulation script that will run in a few minutes using pre-cached simulation tables. You can use this as long as you use a threshold that is either 1.3, 2.0, 2.3, 3.0, 3.3, or 4. This w
