Hi Cathy, Bob,

In line with what Bob said, my script averages all the voxels in an ROI. Let's call this the average ROI value. It then steps through each time point and calculates the average ROI value at each time in your time series. By concatenating each average ROI value into a column, you create the time series.

It sounds like you could just make five different length versions of the script. You will likely have to edit other variables or file names to match those of your own data to get the script to run.

Also, instead of saving the files for editing in excel, you could probably use 1deval to manipulate the individual time series and make averages. I am going to implement that in a newer version of the script, but haven't done it yet.
