PRANA - Polygraphic Recording Analyzer

The PRANA® software for biosignal processing has powerful computing capabilities and modularity allowing multiple software plug-ins to be executed efficiently.

Various software plug-ins for general and specific purposes are already available:

All the software plug-ins can be executed in a single run by using the software plug-in launcher. Additional plug-ins can easily be implemented using the software developer kit.


topArtifact detection

The software artifact detection plug-in allows for automatic signal decontamination by localizing, marking and removing traces containing recording artefacts.

With its graphical interface, this user-friendly and flexible software plug-in features:

Thanks to the software artifact detection plug-in and to its integrated artifact removal procedure, the PRANA® software offers a mean to undertake high-quality signal analyses.


topWaveform detection

The software waveform detection plug-in allows for automatic waveform detection by analysing signals, localising waveforms and marking events from the corresponding traces.
