The best idea I've come up with is to use 3drefit. I had hoped that I could create a file with the data shifted 2 seconds forward, and a second file with the data shifted 2 seconds backward, then at t=2,6,10,14 seconds etc... simply take the mean of the two to get a linear interpolation. Unfortunately, it seems that when files of different start times are added together, the first data point of one is added to the first data point of the other etc... rather than having them add together at each time point. Any thoughts?
Thanks.
