Description

This algorithm dumps on disk a stream from a specific output in the standard GDF file format

Writes incoming experiment information, signal and stimulations data to a file according to the GDF file format. One simply has to connect this box to an output to save the desired streams to a file. For now, only GDF1 files are supported.
