“Neuroinformatics encompasses the tools and techniques for data acquisition, sharing, publishing, storage, analysis, visualization, modeling and simulation” (question from http://incf. org). In this presentation we offer freely available solutions for the first six tasks in the field of biomedical time series. Svarog (Signal Viever, Analyzer and Recorder on GPL, http://svarog. pl) is a multiplatform, open source software, implemented in Java, with user friendly interface and strongly modular architecture. Reading data in different formats is based on the SignalML metadescription of time series (for details see http:// signalml.org and Durka and Ircha 2004). Advanced mathematical methods can be added to the system as plugins. OpenBCI (http://openbci.pl) is an open, multiplatform and multilanguage framework for brain-computer interfaces, which naturally requires online access to the data streams from the amplifier(s). Together, these two systems combine into a complete open source solution for recording EEG in freely designed and fully controllable experimental paradigms. OpenBCI can be viewed as a device driver for Svarog, or Svarog can be treated as a signal viewer for the OpenBCI system. Since 2010, these systems provide complete software platform used in the Laboratory of Biomedical Physics (http:// brain.fuw.edu.pl) for EEG experiments, as well as teaching at the world’s first Neuroinformatics BSc studies (http://neuroinformatyka.pl). As for sharing the data, we propose Poland’s first neuroinformatics portal http://eeg.pl.
