I'm running a Behavioural PLS (E.R. fMRI) analysis with two groups. Each participant completed a GO/NOGO task (75 Go trials, 25 NOGO), done in two runs. One subject only finished a single run, though. I'm running the PLS using only the GO condition, with a temporal size window of 8TR (1 TR = 2 seconds). I decide to average the data across runs.
The behavioural measure of interest is their commission error rate.
I try running this with two groups (young and old adults) and I get the following error:
