The General Data Format for Biomedical Signals is a scientific and medical data file format. The aim of GDF is to combine and integrate the best features of all [biosignal file formats] into a single file format. [GDF v1] can be considered as a successor of the [EDF] file format, but uses a binary header, extended the 16bit limitation of EDF and adds an event table. GDF [v2.0] added fields for additional subject-specific information (gender, age, etc), and utilizes several standard codes (for storing physical units and other properties).
GDF is used mostly in Brain-Computer interface research; however GDF provides a superset of features from many different file formats, it could be also used for many other domains.
The free and open source software library [BioSig] provides implementations for reading and writing of GDF in Octave/Matlab and C/C++.
