GDF 2.0 project site

GDF 2.0 will be the next generation data format for biomedical signals. It will address the future needs for biomedical signal storage and transmission and will contain many new features. This should make the data more valuable. The basic file structure will not change, but the header information header will be encoded more efficiently and many useful information will be added in the header. If you are interested in GDF 1.x (stable version) go here.

Status:

A first prerelease (GDF2.0pre) is available and uses the preliminary version number 1.9x.
