Hi everyone,
I am also working with a similar situation. I have 5 different runs and 3 conditions, which may or may be not present in all the runs. I used the script createVec.m that Donald suggested. It generates the contrasts without a problem. My questions are regarding the setup of the parameters, since I was not able to understand the indications from the comments inside the script.
I don't fully understand what weighted specifies and if I should set it to 0 (as I done to make it work). Also, is there any reason the trialcountmin is set to 30 as a default? In what kind of situation I would need to change that value (I am assuming that it will remain as 30 unless otherwise specified).
Many thanks,
Charles
