Micromed IO library
A library to read, emulate, and forward Micromed data in standard formats. See online doc.
Main features:
simulate online data from a trc file
push online tcp data to LSL server
convert trc to mne format
rename trc files to include the recording datetime
Install
$ pip install micromed-ioConvert a Micromed (.trc) file to MNE (.fif) format
from micromed_io.to_mne import create_mne_from_micromed_recording
mne_raw = create_mne_from_micromed_recording("path/to/file.TRC")Emulate TRC to TCP & read/forward to LSL server
See details in next sections
Emulate Online Micromed TCP from .trc file
$ mmio_emulate_trc --file=../data/sample.TRC --address=localhost --port=5123Emulate the online data stream of Micromed to test your real-time platform. See all the arguments and adapt them:
$ mmio_emulate_trc --help # to see all argumentsRead TCP and push to LSL Stream
$ mmio_tcp_to_lsl --address=localhost --port=5123While receiving online data throug tcp, this command forward the data to 3 LSL stream outlets:
Micromed_EEG: the eeg data in float32 format [n_channels, n_samples]
Micromed_Markers: markers if any in int32 format [sample, marker] (2 channels)
Micromed_Notes: notes if any in string format [sample, note] (2 channels)
You can easily change the LSL parameters:
$ mmio_tcp_to_lsl --help # to see all argumentsRead TRC file
from micromed_io.trc import MicromedTRC
mmtrc = MicromedTRC("sample.TRC")Then you have access to the trc data:
mmtrc.get_header()
mmtrc.get_markers()
mmtrc.get_data()
mmtrc.get_notes()Read and parse Micromed TCP live data
Download tcp_to_lsl.py from the github repo in scripts/
$ python tcp_to_lsl.py --address=localhost --port=5123Note: Micromed TCP behaves as a client. If you want to try the emulate/read TCP script, launch the reader first that acts as server, then the emulator.
Rename TRC files with recording datetime
$ mmio_rename_trc --dirpath=./ --format=%Y%m%d-%H%M%SRename the TRC files of the given folder to include the recording date in the filename. Output is : <filename>__<recording_date>.TRC. The format must be compliant with python strftime format codes
