Hello,

I'm fairly new to imaging analysis and I am trying to develop a new proc script from this one I was given. Right now, this script has 6 contrasts for a reward task, 2 of which are:

wins($1 and $5) vs. no wins ($0)
losses ($1 and $5) vs no losses ($0)

I'd like to separate out each of the magnitudes so there are:
wins ($1) vs no wins
wins ($5) vs no wins
Losses ($1) vs no losses
Losses ($5) vs no losses

What should be changed/added here?
