General Data Format for Biomedical Signals
- General Data Format for Biomedical Signals
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 [http://www.dpmi.tu-graz.ac.at/~schloegl/matlab/eeg/ [biosignal file formats] into a single file format. [http://hci.tugraz.at/schloegl/matlab/eeg/gdf4/TR_GDF.pdf [GDF v1] uses a binary header, and uses an event table. [http://arxiv.org/abs/cs.DB/0608052 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 [http://biosig.sf.net/ [BioSig] provides implementations for reading and writing of GDF in Octave/Matlab and C/C++.
