Here you will find some examples for the usage of libRASCH. For each example the source code for all supported languages is presented.

Initialize libRASCH

This example shows how to start the usage of libRASCH and some basic usage. The following steps will be shown

• init libRASCH
• get number of plugins
• find all measurements in a directory

C-Version -- Perl-Version -- Python-Version -- Matlab/Octave-Version

Access Measurement

This example will show how to open a measurement and how to get some information from a measurement. The following steps will be shown

• open measurement
• get the number of sessions and the maximum sample rate
• get number of informations which are available about the measurement object
• get and print all measurement object infos

C-Version -- Perl-Version -- Python-Version -- Matlab/Octave-Version

Access Recordings

This example will show how to get the root recording and some information about it. The following steps will be shown

• get root recording
• get some general informations about the recording
• get some infos about all used recording devices
• get some infos about all recorded channels

C-Version -- Perl-Version -- Python-Version -- Matlab/Octave-Version

Get Sample Data

This example will show how to get the recorded data. The following steps will be shown

• get raw-data

C-Version -- Perl-Version -- Python-Version -- Matlab/Octave-Version

Access Evaluations

This example will show how to get the evaluation belonging to a measurement and to get some information about it. The following steps will be shown

• get default evaluation
• get some general infos about the evaluation
• get a list of event-properties

C-Version -- Perl-Version -- Python-Version -- Matlab/Octave-Version

Get Events

This example will show how to get values associated with an event. The following steps will be shown

• get RR intervals and the position of the QRS-complexes
• plot the tachogram of the measurement

C-Version -- Perl-Version -- Python-Version -- Matlab/Octave-Version

Usage of Process-Plugins

This example will show how to calculate Heart-Rate-Variability (HRV) using the process-plugin 'hrv'. The following steps will be shown

• get 'hrv' plugin
• calculate HRV using the plugin
• print the calculation results

C-Version -- Perl-Version -- Python-Version -- Matlab/Octave-Version

Usage of view plugins

This example will show how to use view plugins. The example will open a measurement and than display the measurement using the 'ra-view' plugin. This plugin is a wrapper, checking the recorded signals in the measurement and than using best view plugins to display the data.

At the moment only the C/C++ 'versions' of libRASCH can use view plugins. It is planned to add support for view plugins in the other available interfaces.
