[Mne_analysis] epochs with no data?

        External Email - Use Caution        

Hi Dillan,

This can happen when the epochs selected include (theoretical) samples beyond the (actual) data range. You should not have many of those epochs. Can you roughly tell how many no_data labels you found? I‘d need to refresh my knowledge of the epochs reading code a bit to see if there may be other reasons for this. Let‘s see what the others say in the meantime.

Best,
Denis

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. Thank you in advance, again!
