SpiSOP - one tool for all basic sleep EEG analysis

visit http://www.spisop.org

In brief, SpiSOP is free software for most commonly used basic sleep EEG analyses in one easy tool, and facilitates the fast replication of results on large data quanta, as well as enables others to share and communicate the exact methods.

SpiSOP (abrev. for Spindles Slow Oscillation and Power-spectral-density) is an open source tool supporting detection and reporting of spindle or slow oscillation events, their co-occurance or respective matching non-events and power (density) of specific spectra or frequency bands in pre-scored (sleep stages) EEG and MEG data as well as simple automatic EMG artifact detection. Most detection methods and annotations reported in sleep EEG research are covered and thus can be replicated by minor adaptions in the standard parameters.

SpiSOP was designed to process large data quanta at once and multiple datasets in parallel.

Analyses is according to wished channels, their various combinations, specified dynamic sleep stages, various detection thresholds and further parameters.

Frequency peaks in the power band of slow oscillations, spindles or any other band of interest are automatically determined and visually confirmed or adapted by user.

SpiSOP also contains a data browser to sleep (re)score and view sleep EEG data and previously detected events, as well as aids in scoring and detection decisions.

It comes as a standalone command line tool for Windows, Linux and Mac, or can be integrated as toolbox in Matlab.

Read in data and performing spectral analyses is based on the FieldTrip toolbox (GPLv2+, for details see: http://fieldtrip.fcdonders.nl/ or http://www.fieldtriptoolbox.org/).
