You can download the latest update from GitHub. The source code needs to be compiled before you can use the program.
In order to be able to do this, open your package manager and install the Qt4 development package. That's all, your package manager will
take care of all the dependencies and will install the GCC/G++ compiler. For example, on openSuse, start Yast and install the package "libqt4-devel".
On Ubuntu, open a console and enter: sudo apt-get install libqt4-dev libqt4-core g++
Now, open a terminal (console) and cd to the directory that contains the source files and enter the following commands:
make -j16 <enter>
sudo make install <enter>
Now you can run the program by typing: edfbrowser <enter>
The following bugfixes / additions will be available in the next version:
- Added a MIT to EDF+ converter (to convert files from PhysioBank at physionet.org).
Annotations (in the *.atr, *.ari or *.ecg file) will be read and converted to EDF+ as well.
- Docked Power Spectrum: show percentage when using colorbars, in the settingsmenu,
it's now possible to select between auto-gain or manual sensitivity for the colorbars.
- Allow to open multiple docked Power Spectrum windows.
- Correct the screen-offset when inverting a signal that contains a dc-offset.
- Removed a bug that caused a crash when selecting a bessel bandstop/pass filter with an order > 10.
- Increased the maximum number of filters from 8 to 16.
- Added a spike filter which can be used to filter out spikes, glitches, fast transients or pacemaker impulses.
To download the latest snapshot from GitHub, use the following commands:
cd new_source_dir <enter>
git init <enter>
git pull https://github.com/Teuniz/EDFbrowser.git <enter>
In case git is not installed on your system use the following command:
Ubuntu: sudo apt-get install git
Some commandline format converters (without graphical user interface) for scripts or batchfiles.
Note that these converters are also in EDFbrowser.
A very convenient open-source programming library for C/C++ programmers who want to implement EDF(+) and/or BDF(+).
