<br>Dear James & colleagues, <br><div class="gmail_quote"><br>I also have similar questions about eegplot(). I tied using UserData to control the total number of channels displayed by eegplot: <br><div class="im"><br>pop_eegplot( EEG, 1, 1, 1);<br>
</div>ud=get(gcf,'UserData');<br>
ud.dispchans=30; % e.g. 30 channels only<br>set(gcf,'UserData',ud); <br>eegplot('draws',0);<br><br>A "scroll EEG plot" pops out successfully, but only with the last 30 channels of EEG data: there's no scroll button on the left for selecting which 30 channels... Does anyone know if there's a way to add it so that we can scroll channels? Or, instead of always showing last 30 channels, a way to show certain 30 channels? <br>
<br>Another question about eegplot() is that, how can I plot certain channels within certain segments by different color? I image that we could pass the channel number and segments as arguments to eegplot to do that. ( just like the in 'all method' artifact detection, EEGlab plots bad channels in segments in red . ) Does someone have any idea about that? <br>
<br>Thanks in advance!<div><div></div><div class="h5"><br><br><br><div class="gmail_quote">On Mon, Jun 6, 2011 at 2:42 PM, James Desjardins <span dir="ltr"><<a href="mailto:jdesjardins@brocku.ca" target="_blank">jdesjardins@brocku.ca</a>></span> wrote:<br>

Hi Sebastian,<br>
<br>
<br>
Regarding your first question:<br>
<br>
I find it useful to batch interactive pruning procedures as well (if<br>
for no other reason ... it drastically reduces the number of coffee<br>
breaks that I take while pruning data!). To make streamlined<br>
interactive batch scripts I have found that accessing the figure's<br>
UserData is the best way to proceed.<br>
<br>
If your script is already loading the data that you want to display<br>
and edit the following code will (1) create the eegplot, (2) access<br>
the current eegplot's UserData structure, (3) adjust the "winlength"<br>
field of UserData, (4) set the current eegplot's UserData using the<br>
new values, (5) redraw the current eegplot figure with the new values,<br>
(6) wait for this figure to close before continuing on with the<br>
remainder of the script.<br>
<br>
pop_eegplot( EEG, 1, 1, 1); %1<br>
ud=get(gcf,'UserData'); %2<br>
ud.winlength=40; %3<br>
set(gcf,'UserData',ud); %4<br>
eegplot('draws',0) %5<br>
uiwait; %6<br>
<br>
<br>
This procedure is flexible in that any figure properties or UserData<br>
fields can be adjusted in script. For example changing step 4 above to:<br>
<br>
set(gcf,'UserData',ud, 'Position', [1,1,1024,768]);<br>
<br>
... will also move the figure to the bottom-left corner of the display<br>
and change the size to 1024x768 pixels.<br>
<br>
<br>
Regarding your second question:<br>
<br>
The final input to the pop_eegplot function ("reject") when set to 1<br>
allows the immediate removal of marked time periods. When using this<br>
setting simply click the "REJECT" button in the bottom left corner of<br>
the eegplot figure when you are finished pruning and then a separate<br>
call to pop_eegrej will not be necessary.<br>
<br>
I hope that this is helpful.<br>
