Re: [Freesurfer] selxavg3-sess problem: SVD input matrix contains NaN

An epiphany lead me to the solution to the problem, which I shall post here since I am apparently due to experience it again in 2019. The NAN values in the GLM matrices were the result of there being a condition that did not appear in any of the .par files across all of the runs. Once these file

Hi, I'm attempting an inaugural run through the FS pipeline on some event-related data collected over 6 runs. I'm not sure if this makes any difference, but the experiment is self-paced, and the events are of varying duration (it's a lexical decision task, and participants can take up to 4 secon
