[Eeglablist] error in eegplot plugin

[Ian Larger]

Hello,
I have been using the compile version of EEGLAB for the past 2 years
and am only recently trying it through MATLAB. I have been trying to
import the plug-ins eegplot as well as neuroscan.io
When loading EEGLAB I am getting the following error:
eeglab: error while adding plugin "eegplugin_eegplot_w"
Unrecognized field name "check_data".
eeglab: error while adding plugin "eegplugin_neuroscanio"
Unrecognized field name "check_data".

I have checked the code in both files and this is the line that is
flagging the error:

menu = findobj(fig, 'tag', 'plot');
comm = [trystrs.check_data 'LASTCOM = pop_eegplot_w(EEG, 1, 1, 1); '
catchstrs.add_to_hist ] ;
uimenu( menu, 'label', 'Channel data (scroll) +', 'Separator','off', ...
'userdata', 'startup:off;study:off', 'Callback', comm,...
'position',3)

Again, I have virtually no experience with MATLAB itself but do I have
to define the check_data string in the code for my EEG data? If so,
how do I do that?

Any advice is greatly appreciated.
