Python package to read from and write EEG data to European Data Format files.
The EDF standard was introduced in 1992. The extension of EDF with annotations was first described in 1998 and more formalized with the EDF+ standard that was published in 2003. The EDF website describes both standards and discusses implementation details.
Since EDF is such a widely used format, there exist multiple implementations for reading and writing EDF files. Most Python implementations consist of wrappers around the C-code implementation, which makes installation more cumbersome and reduces portability. This implementation is in pure Python with limited dependencies on external packages.
