This is partly what puzzles me, as I would think this would prevent any inclusion of not-real data. My resting state data can be cut into 93 two-second time windows, and this the number of events I am feeding into the epoch object. It is labeling 41 of these 93 as 'NO_DATA'. </div><div><br></div><div>Thank you very much!</div><div><br></div><div>Dillan</div></div><br><div class="gmail_quote"><div dir="ltr">On Fri, Jan 4, 2019 at 3:05 PM Denis A.

I am running into another problem now, however. I am epoching resting state data into arbitrary 2 second windows. I am not automatically rejecting epochs by annotation nor by a rejection parameter. I see that the epoch object's drop_log is recording nearly the whole first half of the epochs as "NO_DATA" epochs, however the raw file contains data for those time indices. I am unsure what could be going on to result in this loss of data, however it seems especially problematic due to the amount of epochs dropped.
