LabRecorder drops data while recording #299

Open ict-ryahata opened 6 years ago

ict-ryahata commented 6 years ago

I'm currently using LabRecorder to record 3 streams of data. The first is a 24 channel EEG headset at 256 Hz, the second is 7 channel data stream of float values at 90 Hz, and the last is a stream of integer markers. All the programs that are generating the streams are running on the same machine that LabRecorder is running on. I am able to successfully record for about a minute but after that no more data is logged. When viewing the outputted file with SigViewer, the length of the recording is correct but the data drops of after a while. When I try to parse the XDF file with the Python XDF script I get an error thrown. File "E:/Python/xdf.py", line 364, in load_xdf jitter_break_threshold_samples,) File "E:/Python/xdf.py", line 533, in _jitter_removal num_samples.append(tmp_duration) AttributeError: 'numpy.ndarray' object has no attribute 'append'

This might be related to #294 (even though the title is misleading, it's mostly about the LabRecorder CPU usage). Could you check with the process manager if the PC is overloaded with LabRecorder while recording the data?
