Ok, so if I use the 4 col I don't need to use -autostimdur, I can use -noautostimdur or can I leave it out all together? I noticed that FIR ignored the stimulus duration entirely, so I only need the -autostimdur/noautostimdur for gamma event related or AB designs? However, I did get a difference

Oh, sorry, I had forgotten when I introduced the 4col format. Yes, 4.5 does take the 4 col. I actually dont remember exactly what 4.5 does when you give it autostimdur with a 4col. It might ignore the duration in the parfile and compute it from the stimulus timing. If you represent all time in

Wait, I'm confused, in v 4.5 (which I'm using) the paradigm files have 4 values per line (starting time, condition, length, and weight), so don't they have the lengths in there? I know you could use an older paradigm file with only 2 columns (starting time, condition), and in this case I would lis

FYI: autostimdur is not valid in version 5.X because the stimulus duration is supplied in the paradigm file. For earlier versions, there was no info in the par file about the duration. The -autostimdur will compute the duration of the stimulus from the paradigm file based upon the time to the n
