# This scriipt demonstrates the visualizer submodule.

# This script should be invoked with the names of the trace files you want to
# use. For example, `gedf_test.py ../sample_traces/*.bin`.
# You probably want to redirect the (normally lengthy) output to a file!
# Otherwise, speed is greatly decreased b/c terminal printing is slow.

# Import the modules we need. You should not need to know about
# their internals.

# Read events from traces
stream = trace_reader.trace_reader(traces)

# Filter out garbage events
stream = sanitizer.sanitizer(stream)

# Note: You could include other submodules, to further modify
# the event stream (e.g. produce G-EDF error records that could be
# drawn by the visuazlier in future versions).

# Print the records to stdout
