Hi Everyone,
I realize a lot has been discussed on this issue on the message board but I'm a little unclear on how to create a peri-stimulus time series based on deconvolution analysis. In other words, I want to measure the signal change over the course of say 18 seconds for each event of interest averaged across all trials of that event type. So, if I have happy, fearful, and neutral faces presented in a fast event related design, I want to plot the average waveform over 18s (assuming a TR of 2s). I want to do this initially on a single subject basis. Is the following correct?
