[Eeglablist] ant and eeglab

[Bernhardsson Jens]

Hi

Importing *.cnt file some events are coded as numbers and some as string, this is a known error and have 
been solved by converting the triggers to either string or number https://sccn.ucsd.edu/bugzilla/show_bug.cgi?id=1161


With the new importer I had to convert from string to number and back to string again in order for eeglab to read 
the triggers correctly.
And in this specific order.

for i=1:size(EEG.event,2);
    EEG.event(i).type=str2double(EEG.event(i).type);
    EEG.event(i).type=num2str(EEG.event(i).type);
    EEG.event(i).urevent=i;
    end;


What kind of a problem can occur, if any, with handling the trigger data like this?
Is there a smoother way to do this?

Also, Arno do you have any clue of the magnitude of event latency problem with the older importer?

Best
Jens

Dear Anahita,

I have noticed a problem with the event latencies of the ANT import plugin.
The event latency were wrong in some case. 
Replace the following function in eeglab/plugins/anteepimport1.08

https://sccn.ucsd.edu/svn/software/eeglab/plugins/anteepimport1.09/pop_loadeep.m

Note that this plugin was originally developed by ANT not by us.
Thanks,

Arno
