Hello Rajyalaksmi, hoping all is well. here's a few notes below, hope you
find them useful. Cheers.
You basically need to get the data into matlab, and then after that make
EEGLAB read it in as a file. You can try the several Importing options on
the EEGLAB gui, such as using the BioSig import. Try/explore the several
general importing functions available there in the gui.
Also, google "Import Data eeglab" and "Import Data eeglablist" to get more
info and ideas. You may also want to google "Brain Tech import eeglab".
After you give it a try a few more times with no success, I would just turn
it your data into a matlab variable, and there I would try to replace build
a new EEG structure in matlab around it. Open a normal EEGLAB file that you
used when you did the EEGLAB tutorial, and review the EEG structure, as you
will have to create a replica of the EEG structure into which you'll put
your EEG data matrix.
You can also find out more about the EEG structure (into which your data
must go) by googling "EEGLAB data structures". Also, don't forget to search
the eeglablist archives for problems similar to your topic, where someone
had to do a special import for some kind of eeg data.
You may also want to try several other EEG software programs' import
functions, or contact the company who made your EEG system for other
options in terms of export or import of the data, or contact any other
researcher who has actually analyzed data from that EEG system in matlab or
eeglab, and they should have the import worked out already.
