Many researchers and programmers have
shared their files and software,
either on an individual basis or in the framework of a larger group or
project. In the name of all EDF users, I sincerely acknowledge their
contributions: they make life a lot easier. This page aims to list all
freely available EDF(+) files and software. Your contribution, too,
will be very much appreciated.
All developers
that are listed on the
contact page offer files and software
Several
companies offer demo versions
of their software
Some European
Projects still keep up their websites

2009. We have
developed a tiny modification of traditional as well as
fullband EEG recorders, so that both can record fullband EEG into
EDF(+). The modification attenuates the DC component, thus reducing the very
large electrode offset voltages,
after which the EEG can be saved into EDF(+). The attenuator is
specified (publication in preparation) in the EDF(+) header. Therefore,
Polyman automatically applies the corresponding un-attenuator (see the
publication) and displays the original fullband EEG. The publication
provides all (rather simple) details, so any EDF(+) viewer or analyzer
can be equipped with this un-attenuator. In this way, fullband EEG
becomes less expensive, suits
non-proprietary software and can be archived independent from the
manufacturer. Test your software with this Fullband EEG sample. Do not
forget to scale your display, because fullband EEG obviously is not
between the traditional +/-100uV levels. If you use Polyman, scaling is
done automatically if you open this Fullband Polyman Template
and then select the sample file.
2008-2009. Our EDF/EDF+ viewer
Polyman
for Win98-Vista,
and some
demo EDF and EDF+ files. First do the Tours that are in the User manual
(see Help).
Please give us your feedback.
Further releases will follow.
2007. Our Microcontinuity analyzer
for sleep slow waves and spindles. Reads one signal from an EDF file
and computes another EDF file in which the 'MC'-labelled signal is
microcontinuity. Article with full algorithms and some applications in
B.Kemp et al, IEEE-BME 47(9), 2000: 1185-1194.
2004.
An EDF/EDF+
to WAV
converter.
This
program converts 1 (mono) or 2 (stereo) signals from an EDF/EDF+ file
into
standard audio (WAV) format. Some results
in compressed (MP3) format.
2003-2005. An
EDF
compatibility
checker.
2004. An
EDF-to-ASCII
converter. Exports one of the signals in an
ASCII
file and all EDF header information, including calibration, about this
signal in an additional
textfile.
2004-2005. Some
calibration
signals
for checking the time and amplitude of your
EDF(+) viewers. They contain sinewaves and blocks of specified
amplitude and
timing. A typical K-complex illustrates EEG polarity and the
"negative-up" rule in Clinical Neurophysiology.
2004-2005. A 20-minute sleep
recording of
a
severe OSAS patient during NREM- and
REM-sleep with annotated QRS complexes.
2002. Some
DOS tools for editing
EDF files: cut and
paste
parts of the data or edit the header.
1993-2003. Our EDF viewer
Polyman for DOS which
includes
manual sleep scoring. Plus a
20-minute EDF file recorded during
sleep
stage 2 and REM-sleep.
