Dear Kaare,

Sorry for slow response and thank you for detailed error report. That
sounds like a real error. Would you please file it to EEGLAB bugzilla? This
is our (renewed) bug report center. http://sccn.ucsd.edu/wiki/EEGLAB_Bugs
Thank you very much again for your cooperation and patience. I guess you
are well capable of finding the workaround, but if there is any immediate
help needed please let us know.

> Dear mailing list. It seems I have discovered an error in pop_chanedit. If
> not, I would very much appreciate instructions regarding how to use it
> properly:
> When deleting a set of channels from my data set I instead get an error
> message:
> ----------------------------------------
> >> EEGtempL=pop_chanedit(EEGtempL,'delete',chanIdxsToRemove);
> Wrong channel structure size, changes ignored
> ----------------------------------------
> The error message is given by 923 in pop_chanedit, and is caused by a
> check of whether the number of channels has changed (nchansori ==
> length(chans), l. 916). But since this is a "delete" call, naturally
> chansori is not equal to length(chans). It seems to be an error that this
> check is performed after l. 580 where the channels were removed.
> I am using eeglab13_4_3b.
