Hi, I'm trying compare the fNIRS data in the first half of the recording to the second half by using the 'Edit Excluded Time' function to block out the time then process and export the data for each half of the session. In the data plot window I can see the areas are highlighted that I want to exclude. However when I export the data, it's identical for the first and second half of the session suggesting that the HRF/data is averaging across the whole session, not over the time points I've selected.

I would be very grateful for any suggestions on how to get the exclude time function working.
