Hi everyone, I'm using optseq2 and a tnullmin of 2 seconds to force 2 seconds between each event for my paradigm, but I get a "segmentation fault" error. Here's my command line below. I didn't specify a tnullmax, so that I would avoid any errors by specifying both. I tried other values for tnullmin like 1, which did work and 1.5, which also did not work. Ideally, the paradigm I would like to model listed in a paper that fixation was jittered 2-10 seconds between stimuli, but 2 seconds does not work for me. Do you know why this might be? Thanks.
