[Eeglablist] FW: reading xltec-produced data

[Makoto Miyakoshi]

Dear Maria,

I would try the following:

1. load that data to Matlab
2. open empty EEGLAB structure by 'eeg_emptyset'
3. write code to copy the items from one structure to the other
4. save the .set file
5. run the above routine for all the files as either a function or .m file

However this does require a bit of Matlab coding... should not be too
difficult though.
