Newbie Question: How to view data in BDF file header

Hello,

I've been tasked with exporting GSR data recorded in our lab to another lab for analysis. Questions have arisen about the GSR amplitudes recorded, and so I now need to determine if our systems were using either the 512Hz or 16Hz SC couplers.

Neither system is currently up and running (in fact, one was on loan from yet another lab), so rather than looking for this information within ActiveView, it seems the best option would be to simply look in field 13 of the BDF file header. And there's the problem: I don't know how to easily view this information.

any help greatly appreciated,
Stephen

The most simple method is to use the file cropper (http://www.biosemi.com/download/Cropper.zip) to extract a BDF file with a length of 1 second, and then to open the this small BDF file in notepad (do not try to open a large BDF file in notepad).

Best regards, Coen (BioSemi)

I know, this reply is a little bit late

An even more simple solution is to open your BDF-file in EDFbrowser

then go to File -> Info to view the header-info.
