<div dir="ltr"><div class="gmail_default" style="color:rgb(51,51,153)">Greetings Yuanjun, Hoping the notes below are useful to you. Cheers!</div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">It depends on what kind of behavioral data you mean. Please remember the eeglab online documentation, previous articles that use the method you want to use, and to try asking google. Here right below are some links I found on the first page of google results after searching for "event information eeglab". Please check them out if you have not had a chance to yet, they should be useful to you.</div><div class="gmail_default" style><font color="#333399"><a href="http://sccn.ucsd.edu/wiki/A02:_Importing_Event_Epoch_Info">http://sccn.ucsd.edu/wiki/A02:_Importing_Event_Epoch_Info</a></font><br></div><div class="gmail_default" style><font color="#333399"><a href="http://sccn.ucsd.edu/wiki/Chapter_03:_Event_Processing">http://sccn.ucsd.edu/wiki/Chapter_03:_Event_Processing</a><br></font></div><div class="gmail_default" style><font color="#333399"><a href="http://sccn.ucsd.edu/wiki/A05:_Data_Structures">http://sccn.ucsd.edu/wiki/A05:_Data_Structures</a><br></font></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">Usually, researchers have information per each single trial</div><div class="gmail_default" style="color:rgb(51,51,153)">that specifies the kind of stimuli, the kind of responses that happened, and/or other information. You could do this with eeglab in at least three ways. Some of these methods require some matlab coding on your part.</div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">One way would be to add the information to event fields for each epoch. </div><div class="gmail_default" style="color:rgb(51,51,153)">Then you can, for example, sort the trials with the erpimage function using the single-trial information. You can also then, do new epoching based on that behavioral information. </div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">Another way would be to create a study that has conditions or groups that are related to your behavioral data (for example, the angry condition and the sad condition, or the high performing and low performing groups). Then you would be able to view the data in eeglab study, convolved with the behavioral data dimensions you have chosen to focus on.<br></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">Another way is to use matlab to have a structure of information that contains all your "behavioral" information, that you can relate to continuous or epoched eeglab file you have in memory. This depends on your ability to work inside matlab to coordinate the information. Once you have estimates from eeglab for single trials, or per participant, then you can compute the eeglab metrics (for single trials or single files) and then compare to the behavioral information you have within matlab, using your own matlab codes.</div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">It's not clear what the "soft of SCAN" is ?</div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">If you have advanced behavioral data such as motion capture, consider the MOBI eeglab toolbox from Ojeda.</div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Apr 9, 2015 at 4:39 AM, - - <span dir="ltr"><<a href="mailto:xieyuanj@gmail.com" target="_blank">xieyuanj@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><span style="font-size:14px">Hi EEGLab users and experts,</span><br><div><span style="font-size:14px"><br></span></div><div><span style="font-size:14px"> I would like to check the relationship between behavior data and eeg data,so i want to merge the behavior data into the eeg dataset using eeglab.
