mne.io.read_raw_mef

mne.io.read_raw_mef(fname, *, password='', preload=False, verbose=None) → RawMEF

Read raw data from MEF3 files.

Parameters:

fnamepath-like

Path to the MEF3 .mefd directory.

passwordstr | bytes | None

Password for encrypted MEF sessions. Use an empty string for unencrypted data.

preloadbool or str (default False)

Preload data into memory for data manipulation and faster indexing. If True, the data will be preloaded into memory (fast, requires large amount of memory). If preload is a string, preload is the file name of a memory-mapped file which is used to store the data on the hard drive (slower, requires less memory).

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns:

rawinstance of RawMEF

The raw instance. See mne.io.Raw for documentation of attributes and methods.

Notes

New in v1.12.

Data is read using the pymef package.

Channel types default to sEEG (stereo-EEG). Use raw.set_channel_types() to set appropriate types after loading.

Examples

Read a MEF3 file:

>>> raw = mne.io.read_raw_mef('recording.mefd')
