The File Reader reads data from a local file. It iscurrently only compatible with files saved in the KWIK format (specifically KWD files storing continuous samples), which can either be saved directly from the Open Ephys GUI or from another program. There are four example files included in the GUI repository that can be used with the FileReader, found in the the Resource/DataFiles directory (source code download) or the the DataFiles directory (executable download):
- data_stream_16ch_cortex.kwd - data from 8 stereotrodes (16 channels total) recorded from barrel cortex of an awake mouse. The signals contain a bunch of single units, and can be used to test out the Spike Detector
- data_stream_16ch_hippocampus.kwd - one channel of data recorded from CA1, copied across 16 channels. The signals have large-amplitude theta oscillations, and can be used to test out the Phase Detector.
- data_stream_sine_wave.kwd - 16 channels of a simple, 1000-microvolt sine wave. There's a small glitch near the end.
- chirps_16_channels_At40kHz.kwd - 16 channels of frequency sweeps at 40 kHz
...
If there are multiple recorded segments within the file (i.e., recording was stopped and restarted), you can choose which segment you want to play back using the drop-down menu.
You can also choose a subset of your recorded file by changing the "start" and "end" times at the bottom of the File Reader editor.
