European Data Format (EDF) conversion

Highlighted

The European Data Format (EDF and EDF+) is a popular format for saving biomedical signals and has become a de facto standard interchange format for EEG and PSG data.   It consists of a text header containing signal information, channel labels, calibration data, and information about how the data is formatted, followed by a 16-bit binary data stream, or two-dimensional array, with the actual signal data.  The EDF+ format was added in 2002 to include additional features, including channel annotations (time-coded notations), support for discontinuous data files, and other features.

More information about the standard and the file specifications can be found here:  http://www.edfplus.info/specs/index.html

The new Biomedical Starter-Kit includes a mini-app to import EDF and EDF+ format and save to a variety of standard formats that are easy to work with in LabVIEW.

There is also a DataPlugin for DIAdem located here:  http://zone.ni.com/devzone/cda/epd/p/id/2642

Here's some information from Brad Turpin about using the EDF DataPlugin with LabVIEW:

Hi Steve,

The existing "EuropeanDataFormat" DataPlugin will work in LabVIEW. If you look at the top of the http://zone.ni.com/devzone/cda/tut/p/id/4065 web site, you will see a link ("Loading Data with a DataPlugin Within LabVIEW") to a LabVIEW VI that calls DataPlugins using the Storage VIs.

The input string you need to use for the DataPlugin name is "EuropeanDataFormat",

Brad
