Latest ActiView  |
| ? |
ActiView is the acquisition program for the ActiveTwo system. It is an open source program written in LabVIEW. |
| ? |
For users without LabVIEW, an executable is also included. You need the LabVIEW runtime engine when you want to run the ActiVIEW executable without LabVIEW. ActiView is available in various screen resolutions for the most common laptop and desktop monitors. If your monitor has a lower resolution then the selected ActiView, you will only see a plain gray screen. When you want to go to the source code of ActiView, go to the about tab and then click on the red square. |

LabVIEW Runtime engine 8.6.1 (95mB) (ActiView versions 7 or higher)
The runtime engine allows you to run LabVIEW 8 executables without needing further LabVIEW on your PC. Download this zip file and install it on your PC. Read here for more information about BioSemi LabVIEW executables. |

| Free programs from third party developers: |
|
OpenViBE: OpenViBE is a free and open source software platform dedicated to designing, testing and using brain-computer interfaces. OpenViBE is software for real-time neurosciences (that is, for real-time processing of brain signals). It can be used to acquire, filter, process, classify and visualize brain signals in real time. |
|
EEGLAB Toolbox : MatLab EEG toolbox (Delorme & Makeig) |
| ? |
Open source interactive Matlab toolbox for processing continuous and event-related EEG data using independent component analysis (ICA) and time/frequency analysis including artifact rejection. |
|
ERPLAB Toolbox: Open source Matlab package for analyzing ERP data |
| ? |
ERPLAB Toolbox is tightly integrated with EEGLAB Toolbox, extending EEGLAB’s capabilities to provide robust, industrial-strength tools for ERP processing, visualization, and analysis. A graphical user interface makes it easy for beginners to learn, and Matlab scripting provides enormous power for intermediate and advanced users. |
|
Fieldtrip: |
| ? |
Matlab software toolbox for MEG and EEG analysis. (FC Donders Institute)
Fieldtrip includes algorithms for simple and advanced analysis of MEG and EEG data, such as time-frequency analysis, source reconstruction using dipoles, distributed sources and beamformers and non-parametric statistical testing. It supports the data formats of all major MEG systems (CTF, Neuromag, BTi) and of the most popular EEG systems, and new formats can be added easily. |
|
BIOSIG: EEG review toolbox (Schloegl) |
| ? |
The following tools are available free for download:
– Biosig for Octave and Matlab (biosig4octmat) – For accessing (reading and writing) of several data formats
– Biosig for C/C++ – a C/C++ library (libbiosig) for reading, writing and converting (save2gdf) various data formats
– BioSig for Python – provides an interface to python for reading BDF data (based on Biosig4c++)
– SigViewer – A Viewing and Scoring Software, which can handle also BDF data. |

Polyrex BDF file-format to Neuroscan CNT file-format converter. (J?rgen Kayser) |
|
MatLab code to read BioSemi BDF format data files. (Scholte) |
|
EDFbrowser  |
| ? |
A free, opensource, multiplatform, universal viewer & toolbox intended for, but not limited to, timeseries storage files like EEG, EMG, ECG, BioImpedance, etc. |
|
C/C++ Library for reading EDF/EDF+/BDF/BDF+ files (Teunis van Beelen) |
|
Java library for tcpip streaming (client & server) (Gido Hakvoort) |

| Utilities from BioSemi:(LabView RunTimeEngine 8.6.1 needed) |
|
BDFreader |
| ? |
This simple file reader can be used to check your recorded BDF files. |
|
TCPIP client Application
This LabVIEW program receives the data being sent over TCPIP by ActiView. |
|
BDF to EDF converter |
| ? |
Some brain analyzing products are technical incapable of reading high resolution 24 bit BDF files with full DC data. You can use this utility for converting your BDF files to 16 bit AC (high-passed) EDF files. |
|
FileCropper |
| ? |
This utility can be used to crop large BDF files into smaller files.
It also can be used to repair BDF files with a wrong length value written in the header. |
|
Decimater (downsample .BDF files) |
| ? |
This utility can be used to decimate (downsample) your BDF file into a smaller file.
Sample rate and bandwidth can be reduced by a factor of 2 or 4 or 8. A fifth order sinc filter is used to prevent aliasing. |
|
File Merger |
| ? |
The Merger is used for merging 2 .bdf files into 1 .bdf file. |
|
Reducer Tool
|
| ? |
Tool to reduce the number of channels in a BDF file. Free choice of channels to be converted to the new BDF file. |
|
BDF Repair Tool |
| ? |
If the PC crashes during acquisition, the BDF header will not list the correct file length. Some review programs may crash on such an incorrect BDF file header. In addition, the above tools can also not process files with an incorrect header. This repair tool corrects the file length in the header. |
|
Acquisition-core (ActiView Light) of the ActiView program. Made with LabVIEW 8.2 |
| ? |
This allows LabVIEW developers to built their own acquisition program by just using the basic acquisition core of ActiView. The core just reads the ring-buffer and provides the incoming data and trigger/status channel as array ready for further processing. The code also gives insight in the basic setup of ActiView. |
