I have recorded EOG in .eeg format. I want to convert .eeg file to .mat file in matlab for analysis. anyone know how to convert it?
Hi Chirag,
I assume you talk about the BrainVision .eeg file format. It comes together with a .vhdr file in the same directory. Using matlab, you can download the eeglab toolbox
http://sccn.ucsd.edu/eeglab/, it comes with a plugin toolbox (bva-io) to handle BrainVision file formats.
Using this toolbox, you can just type:
res=pop_loadbv('yourfile.vhdr');
to load all the information in a matlab structure. In particular, res.data contains the signals in a matrix (channels x samples).

And I would like to add to Michel's comment that make sure the file name has only English characters.
Just load that .eeg file in Matlab with appropriate file reading process and save that EEG signal variable. The saved file is .mat file with the variable name.
You can use the following function within matlab to load the *.eeg file:
http://sccn.ucsd.edu/~arno/programs/loadeeg.m
To use it, just write:
signal = loadeeg( 'myfile.eeg' );
To save to a matlab file, just write:
save myfile.mat signal
