Hi Pete,

erating this but ERSP plotting worries me and so I feel bad I took so much time working on it but I do have slightly more peace of mind knowing we dug in and uncovered some issues.

Anyways I am back tomorrow so shall we meet on Monday at 12:30 / 3:30?

Subject: [Eeglablist] Error when plotting std_erspplot

Hello eeglab list:

When using 'std_erspplot' from the command line or the gui

The figure correctly displays all channels in a single plot, but when I click on a specific channel, I get the following error:

"Error using str2num (line 32)
Requires string or character array input.

Error in copyaxis (line 97)

Error while evaluating Image ButtonDownFcn"

The individual channel ERSP plot will then have a wildly incorrect axis on the freq side. We recently upgraded from R2012 to R2014b so I wonder if that is the issue, as there is no problem when plotting in R2012 (the individual channel figure would pop up correctly in a new window).

Here are the parameters I normally use:
[STUDY, allersp, alltimes, allfreqs] = std_erspplot(STUDY,ALLEEG,...
    'channels',{'Cz' 'E1' 'E2' 'E3' 'E4' 'E5' 'E6' 'E7' 'E8' 'E9' 'E10'...
    'E11' 'E12' 'E13' 'E14' 'E15' 'E16' 'E17' 'E18' 'E19' 'E20' 'E21' ...
    'E22' 'E23' 'E24' 'E25' 'E26' 'E27' 'E28' 'E29' 'E30' 'E31' 'E32' 'E33'...
    'E34' 'E35' 'E36' 'E37' 'E38' 'E39' 'E40' 'E41' 'E42' 'E43' 'E44' 'E45'...
    'E46' 'E47' 'E48' 'E49' 'E50' 'E51' 'E52' 'E53' 'E54' 'E55' 'E56' 'E57'...
    'E58' 'E59' 'E60' 'E61' 'E62' 'E63' 'E64'});

Has anyone else encountered this issue?

I am running:
eeglab 13.4.4b
Matlab R2014b
Win 7 x64

Thank you all,
