Hi there,

I want to have 98 experimental trials for the each of the experimental trials for the nback (2 keys) followed by slider trial. However, I noticed in my output that they are not always 98. The sequence is as follows (not including slider trial):
- 1back = 98 experimental trials
- 2back = 99 experimental trials
-3back = 100 trials
Is it possible to have the 1back, 2back, and 3back all have 98 experimental trials? My code for trials is below, please let me know if you need my full script or any additional information. I'd appreciate any help!
1 = start;
    2 - 98 = noreplace(nontarget, nontarget,target);
    99 = slidertrial.nbackperception;
