Re-sample Data

If you have a large data set that is too big to handle, one option is to downsample it. In this macro, the data is averaged every x number of points. You will loose resolution, but gain with some noise reduction.  Also, many times I suggest for people to collect more data and filter or clean it up later (storage space for data is basically free these days)… recreating the experiment is usually more expensive than a flash drive.
