Not really. You can force there to always be a NULL with --tnullmin. You can also specify the maximum duration of the null event with --tnullmax; this should indirectly cause there to be more instances where nulls appear between non-nulls.

Greetings,

Is it possible to avoid having Optseq repeat my events more than 3 times before inserting a NULL? In other words, I get sequences that look like ev1, ev5, ev4, ev2, ev6, NULL, etc. Ideally, I'd have Optseq limit event repetitions at 2-3 followed by a NULL. I tried using "-repvar" but I don't really understand how to use it, or whether the function will help. I've provided my syntax below.

Thank you,

Joseph

./optseq2 --tr 2 --ev SocialFear 8 6 --ev NonsocialFear 8 6 --ev SocialSad 8 6 --ev NonsocialSad 8 6 --ev SocialNeutral 8 6 --ev NonsocialNeutral 8 6 --o SituatedNeuroscience --nkeep 30 --nsearch 10000 --psdwin 0 26 1 --ntp 180 --repvar 8
