An in important aspect in the future developement of BIOSIG is the encoding of events, markers and annotations.

The approach within BIOSIG, is a ono-to-one code-table according to biosig/t200/eventcodes.txt. The events are grouped into several problem-specific classes. All events are encoded in 16bit integer numbers, the highest bit encodes On- and Offset. The latest version of the table of eventcodes is available at:

The table is prepared for extension to other application areas, as well. Therefore, I'm asking you for suggestions on the extension of the table.

The event encoding is also supported by the powerful viewing and scoring software SVIEWER which is part of BIOSIG. SVIEWER has all the standard features of a viewer (e.g. scrolling, scaling, etc). Additionally, event and marker information can be edited.
