[Eeglablist] importing the events

[Makoto Miyakoshi]

Dear Ed,

> is this procedure is correct procedure: after loading the data, I load
the file of channel location, then I do "Re-reference".

No, because you want to check if the channel you are going to re-reference
is clean or not. We recommend average reference, which means all the
channels should be clean.

And I get the evens number displayed perfectly.

Looks like your data has event numbers in channels. If it works fine do so.

method you proposed. In other words, where we can find and display both
type and latency first, so that we can use them in the created Excel file
and then save the file as a text one?

I thought you have event file contents separately. However, that sounds
like you have all event info in the channels. If this is the case you need
to import it with appropriate protocol.

I don't remember exactly, but if it supports .txt files, it probably works.
