[Eeglablist] artifact detection

[Brittany Alperin]

Hello

I'm running into an issue with artifact detection (an ERPLAB function)
although my error seems to be an EEGLAB error.

I have epochs time locked to an event that are -12200 to 0 ms. I'm using a
simple voltage threshold for that time range for all channels at -90 90 uV.
I've done this without an issue on data with a more standard epoch range
(e.g., -200 to 1000). When I try to run this in Matlab 2016b with the most
recent versions of ERPLAB and EEGLAB, it works, but if I want to
interpolate a channel and then artifact detect, I get the following error:

Expected one output from a curly brace or dot indexing
expression, but there were 0 results.

Error in markartifacts (line 118)
                  EEG.EVENTLIST.eventinfo(itemzero).flag =
                  newflag;

Error in pop_artextval (line 243)
                        [EEG errorm]= markartifacts(EEG, flag,
                        chanArray, ch, i, isRT);

If I run this in Matlab 2012b using ERPLAB 6.1.3 and EEGLAB 12.0.2.6b. I
get the same line error, but it says:  "Illegal right hand side in
assignment. Too many elements."

Again, it works as long as I don't interpolate a channel, but I'm not sure
why that would be. Any insights?

Thanks,
Brittany
