General Data Format for Biomedical Signals
Encyclopedia
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] uses a binary header, and uses 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++.
File format
A file format is a particular way that information is encoded for storage in a computer file.Since a disk drive, or indeed any computer storage, can store only bits, the computer must have some way of converting information to 0s and 1s and vice-versa. There are different kinds of formats for...
