MNE Realt-time Server on Neuromag Linux

WARNING: Be careful when modifying the production system!

In Short


  1. Create folder na-online, na-online/mne-cpp_dependencies, na-online/mne-cpp_dependencies/qt5 in home
  2. Get Qt5
  3. Setup Qt5
  4. Get MNE-CPP
  5. Compile MNE Realt-time Server
  6. Start mne_rt_server

1. Prepare Neuromag Workstation


cd ~
mkdir na-online
mkdir na-online/mne-dependencies

2. Get and Setup Qt5


Download Qt5 code. You may have to do it on another workstation with git!

# Workstation with git
cd ~
mkdir ~/mne-cpp_dependencies
cd ~/mne-cpp_dependencies
git clone git://gitorious.org/qt/qt5.git qt5_repository
cd qt5_repository
git checkout v5.1.1
./init-repository --module-subset=qtbase
# Neuromag workstation
cd ~/na-online/mne-cpp_dependencies
scp -r <user>@<git workstation>:~/mne-cpp_dependencies/qt5_repository ./

There is a problem with the Linux (CentOS/RedHat kernel 2.6.18) of the Neuromag workstation: linux/futex.h ... undecleared Solution:

cd ~/na-online/mne-cpp_dependencies/qt5_repository
# Modify: qmutex_linux.cpp
nano qtbase/src/corelib/thread/qmutex_linux.cpp
#include <linux/futex.h> // replace this line ...
// ... with this two defines
#define FUTEX_WAIT 0
#define FUTEX_WAKE 1

Configure and compile Qt5 on Neuromag workstation:

mkdir ~/na-online/mne-cpp_dependencies/qt5
cd ~/na-online/mne-cpp_dependencies/qt5_repository
# Configure
./configure -prefix ~/na-online/mne-cpp_dependencies/qt5 \
-confirm-license -opensource -release \
-nomake tests -nomake examples \
-no-icu -no-glib -no-sql-sqlite \
-no-libjpeg -no-libpng -no-gif \
-no-gui -no-widgets \
-qt-zlib -qt-pcre
# Compile and install
make -j8
make install

3. Get and setup MNE-CPP and MNE Real-time Server


Download MNE-CPP code. You may have to do it on another workstation with git!

# Workstation with git
cd ~
mkdir ~/na-online_dependencies
cd ~/na-online_dependencies
git clone https://github.com/mne-tools/mne-cpp.git
# Neuromag workstation
cd na-online
scp -r <user>@<git workstation>:~/na-online_dependencies/mne-cpp ./

Compile MNE library:

cd ~/na-online/mne-cpp/MNE
# Modify: MNE.pro
# Comment out lines with disp and disp3D
<path to qt5>/bin/qmake -r
make -j8

Compile MNE Real-time Server:

cd ~/na-online/mne-cpp/applications/mne_rt_server
<path to qt5>/bin/qmake -r
make -j8

4. Start MNE Real-time Server


Open the ports 4217 and 4218 in the firewall.

cd ~/na-online/mne-cpp/bin
export LD_LIBRARY_PATH=~/na-online/mne-cpp/lib
./mne_rt_server
