PhiTools: Software Tools for Physiology

PRANA Viewer

From a graphical user interface, the PRANA® Software Suite's Viewer program allows quantitative and visual analysis of multiple polygraphic signals using various montage, re-referencing, filtering options as well as artifact correction and signal denoising based on blind source separation (BSS).

Reviewer for PSG scoring and qEEG analysis

Its complete navigation and search tools ensure a fast and easy recording reviewing and interpretation. Recording annotation and stage scoring can be undertaken easily by simple mouse-clicks and keybord key-presses inserting markers and scores directly from the traces. The PRANA Viewer program also offers an expert scoring system adapted to various classification rules (human/animal sleep and vigilance analysis, haemorrhagic shock, anaesthetic depth, etc.). Any recording portions can be scored by several experts on an epoch-by-epoch basis with selectable epoch durations.

A series of additional graphically interfaced modules accompany the PRANA® Software Suite for polysomnography and biosignal processing. These optional software plug-ins feature general to specific time-varying or event-related quantitative biosignal analysis as well as various transient event and pattern detection methods. Report generators can instantly edit and print comprehensive study reports available as portable computer files including data statistics and graphical representations.

Interoperability

The PRANA® Software Suite supports various data-formats and can be used with digital recordings from virtually any computerized acquisition systems allowing full interoperability between collection and analysis systems.

Export time series

European Data Format recordings (*.edf) from the EDF consortium.
LORETA EEG/ERP files (*.lor) from the KEY Institute for Brain-Mind Research.
MATLAB binary files (*.pra).
Raw binary int16 files (*.bin).
Standard ASCII text files (*.txt).

A software-specific ASCII file format with tabulation separators and standard headers containing all the information necessary to encode various data types ensures exporting and importing the results obtained from any analysis or detection software plug-ins. All results can be opened using any text-file editor (Notepad, Write, etc.).
