OK, I've looked at the educational material that you directed me to and have a better idea of the options.
I used the default "Cox special" basis function in my waver script. Because I'm working with normalized data, I set the peak to be 1.
if I want to plot the response for a particular regressor, could I simply multiply the beta value in the output dataset a 1D waver output file for that regressor, rather than use 3dcalc with the basis function (which seems pretty complicated, given its formula on the FAQ)?
Thanks--
