EDFChannelInfo

Namespace: BIDSLIB  ·  Library: BIDS Library

#include <bids/bids_edf_reader.h>

struct BIDSLIB::EDFChannelInfo

Channel-level metadata from the EDF header.

src/examples/ex_bids/main.cpp
const QVector<EDFChannelInfo> edfChannels = static_cast<EDFReader*>(edf.get())->getMeasurementChannelInfos(); // header fields per signal

Public Methods​

toFiffChInfo()​

toSi()​

Returns:

  • float — Factor from the physical dimension to SI (µV/uV 1e-6, mV 1e-3, otherwise 1; 1 for a "Status"/"Trigger" stim channel), as in mne read_raw_edf.

Example​

Used in examples​

ex_bids​

BIDS library: paths, sidecar TSVs, BrainVision/EDF readers and a raw-data round trip.
