[Eeglablist] Error in pop_epoch command line

[Kelly Michaelis]

Hi John and Ramon,

Thank you for your responses.

I actually tried doing it through the GUI and using the eegh script, but
that produced the same error. It seems the issue has to do with the
presence of boundary events in a dataset - the command line function fails
on any dataset that has boundary events.

I submitted a bugzilla report:
https://sccn.ucsd.edu/bugzilla/show_bug.cgi?id=13798

I've been playing around with it. It seems it's a data type error arising
from line 216.

Ieventtmp = [ Ieventtmp ; strmatch(tmpevent, tmpeventtype, 'exact') ];

I switched the strmatch for contains, and this seems to have fixed the
error.

Ieventtmp = [ Ieventtmp find(contains(tmpeventtype,tmpevent))];

If anyone else is having this issue, you may want to try this.

Thanks,
Kelly
