Developers of EDF and EDF+ software
Many developers, companies and research groups apply EDF(+).
Those that offer unrestricted EDF(+) files or data are listed here.
European research projects are at the bottom.

2006-2008. Teunis van Beelen made (all open source) EDF+ software, including an EDF+ browser, an EDF/EDF+ compatibility checker, a Nihon Kohden to EDF/EDF+converter, and a (multichannel multifrequency) EDF to ASCII converter.

2003-2007. George Moody at Harvard-MIT division of Health Sciences and Technology made an open-source MIT-EDF and EDF to MIT converter. His large database of physiologic signals contains 8 sleep recordings with hypnograms and some multichannel fetal ECG recordings with QRS annotations.

1990-2007. Bob Kemp co-developed and published EDF and EDF+. He maintains these EDF webpages. Bob and his colleague Marco Roessen made EDF(+) files and EDF(+) software including the EDF/EDF+ viewer Polyman, an EDF header checker, and some files for amplitude calibration.

2003-2006. Raphael Schneider made the open source software libRASCH, for viewing and analysis of signals in many formats including EDF and EDF+.

2003-2006. Nizar Kerkeni made the Java EDF viewer jEDF, for viewing and analysis of signals in EDF.

2002-2006. Jesus Olivan at the Hospital Carlos III, Clinical Neurophysiology Unit, Madrid, Spain, co-developed EDF+ and made software, data and tutorials for EDF and EDF+ (including discontinuous EDF+).

2004. Thomas Noessler made the open source EDF software SleepExplorer for review and analysis of EEG and polygraphic recordings.

2004. The OpenXDF consortium made an XDF viewer that also reads EDF files. Warning: the viewer automatically makes an XDF copy of your EDF file in the same directory.

1999-2004. Alois Schloegl, Graz University, Austria, made open source EDF tools for Matlab. See also Alois's pages at Sourceforge.

2004. Patrick Berg at the University of Konstanz made some discontinuous EDF+ files. The d22.. file is not completely EDF+ because its records are not in chronological order, but this makes it a very nice file for testing.

2004. Teuvo Sihvonen, Pekka Sihvonen, Sami Kuusrainen and Tapio Grönfors at the University of Kuopio, Finland, are developing lightweight embedded systems that record in EDF/EDF+. Some discontinuous EDF+ testfiles.

2004. Alex B Samardzic made the open source EDF software TEMPO for animated 3D topographic maps of EEG.

2004. The Institute for Neural Computation at the University of San Diego made EEGlab, an open-source Matlab toolbox for processing of EXG and events that can import EDF.

2000. Die Deutsche Gesellschaft für Schlafforschung und Schlafmedizin DGSM provides some EDF software made by Alpo Värri.

1990-1997. Alpo Värri at Tampere University of Technology, Finland, co-developed EDF and made the first EDF programs.

European projects

The 6th Framework project SAPHIRE (8 groups from 5 countries, 2006-2008) exchanges pulse-oximeter and ECG recordings using EDF.

The integrated project SENSATION (43 groups from 18 countries, 2005-2008), subproject 1, is making ambulatory 24-48 hour EDF recordings of sleep, wake, vigilance and attention in 100-200 healthy volunteers.

The Biomed-2 program SIESTA (15 groups from 7 countries, 1997-2000) has built a multi-center database of sleep (questionaires and 2 polygraphic EDF sleep recordings) and wake (psychometric tests, questionnaires) data in about 200 volunteers and 100 patients. This database is now kept by The Siesta Group GmbH (see companies).

The Biomed-2 program IBIS (12 groups from 6 countries, 1997-2000) provided the last version of the EDF viewer WinDisp (made by Carsten E. Thomsen) and some other EDF tools.

The European Neurological Network (ENN: 40 groups from 11 countries, 1995-1998) has made available 20 patient recordings in EDF and a Java applet which enables viewing and analysing the recordings through an internet browser.

The Biomed-1 program IMPROVE (12 groups from 11 countries, 1994-1997) used EDF to record signals in critical care conditions. Their website had EDF data and the WinDisp EDF viewer for Win95 and Win3.x, made by Carsten E. Thomsen.

EDF was developed in 1991 within the COMAC-BME Concerted Action on "Methodology for the Analysis of the Sleep-Wakefulness Continuum".
