Developers of EDF(+) software and providers of
EDF(+) recordings
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.
Please inform me if you should (not) be on this list!
Bob
Kemp
2006-2009. Teunis van Beelen made
open source EDF+ software, including an EDF+ browser, an EDF/EDF+
compatibility checker, a Nihon
Kohden
to EDF+ and an EMSA to EDF+ converter, a (multichannel
multifrequency) EDF to
ASCII converter, a C/C++
library to read and write EDF/EDF+ files.
2009. Teunis van Beelen also made opensource hardware, a 12-channel ADC converter,
that writes EDF+.
1990-2009. 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.
2003-2008. 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.
1999-2008. Alois Schloegl, Graz
University, Austria, made Matlab tools and the open source SigViewer
for browsing and scoring recordings, all for various formats including
EDF, all at Sourceforge.
2006-2008. Horace Townsend provides
a website for EEG
education, containing a web-based viewer that lets you browse
through a selection of EDF
recordings. Registration is needed.
2004-2008. The OpenXDF consortium (Neurotronics
Inc) made an
XDF
viewer that also reads EDF
files.
2003-2007. The SERC at Case Western Reserve
university made about 1000 (!) PSGs in EDF available for download.
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. 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. 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.
1990-1997. Alpo Värri at Tampere
University of Technology, Finland,
co-developed
EDF and made the first
EDF programs.
European
projects, listed till 2008 only
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".
