Latest patches & additions

The following bugfixes / additions will be available in the next version:

- EMSA to EDF converter: fixed a bug that could cause a crash due to invalid free-ing of memory.
   Fixed a bug that could cause to write an invalid character into the EDF header when a signallabel
   name is shorter than 16 bytes.
- Export filtered signals: include Z-ratio filter.
- Spectrum Analyzer: add the possibility to change the DFT block size on the fly.
- Spectrum Analyzer: add the possibility to select rectangular, Hamming or Blackman window.

If you don't want to wait till the next version, follow the instructions below in order
to use the latest bugfixes & additions.

Compiling

- Install Git, the GCC compiler, make and the Qt4 development package:
Linux Mint 18: sudo apt-get install git-core g++ make libqt4-dev libqt4-core
Ubuntu 17.10: sudo apt-get install git-core g++ make libqt4-dev
openSuse Leap 42.3: sudo zypper in git-core libqt4-devel
Fedora 25: sudo dnf install git-core qt-devel gcc-c++

- Download the source code:
mkdir EDFbrowser_git
cd EDFbrowser_git
git init
git pull https://github.com/Teuniz/EDFbrowser

- Create the makefile:
Linux Mint 18: qmake
(K)ubuntu 17.04: qmake
openSuse Leap 42.2: qmake
Fedora 25: qmake-qt4

- Compile the source code and install it:
make -j16
sudo make install

Now you can run the program by typing: edfbrowser

Other EDF software
