<div dir="ltr">Dear Liz,<div><br></div><div>I think I know the issue. This is the limitation of the current EEGLAB, so it needs to be fixed by changing the current design by the developers. To do so, I need to ask you to file the case to the eeglab bugzilla.</div><div><a href="https://sccn.ucsd.edu/bugzilla/enter_bug.cgi">https://sccn.ucsd.edu/bugzilla/enter_bug.cgi</a><br></div><div><br></div><div>I appreciate your patience and cooperation.</div><div><br></div><div>Makoto</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Apr 12, 2016 at 7:17 AM, Liz Chrastil <span dir="ltr"><<a href="mailto:chrastil@bu.edu" target="_blank">chrastil@bu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><span style="font-size:12.8px">Hi EEGers</span></div><span style="font-size:12.8px"><div><span style="font-size:12.8px"><br></span></div>I'm running into an error when I segment, remove the baseline using pop_rmbase, and reject bad trials. I am trying to use the entire epoch as the baseline. It works fine for most conditions, but when I come to a condition that only has a single instance of condition I run into this error (see end of message). I went through using the gui and it looks like it is only a problem when I have a single instance of a condition. My experimental setup will have several times of single trials within a condition because I want to combine them at a later time in different ways.</span><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">How can I get around this error?
