mne.io.read_raw¶

mne.io.read_raw(fname, *, preload=False, verbose=None, **kwargs)[source]¶

Read raw file.

This function is a convenient wrapper for readers defined in mne.io. The correct reader is automatically selected based on the detected file format. All function arguments are passed to the respective reader.

The following readers are currently supported:

read_raw_artemis123, read_raw_bdf, read_raw_boxy, read_raw_brainvision, read_raw_cnt, read_raw_ctf, read_raw_edf, read_raw_eeglab, read_raw_egi, read_raw_eximia, read_raw_fieldtrip, read_raw_fif, read_raw_gdf, read_raw_kit, read_raw_nicolet, and read_raw_nirx.

Parameters

fnamepath-like: Name of the file to read.
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.
**kwargs: Additional keyword arguments to pass to the underlying reader. For details, see the arguments of the reader for the respective file format.
