, system_clock='truncate', preload=False, verbose=None)[source]

Raw object from CTF directory.


directory : str

Path to the CTF data (ending in '.ds').

system_clock : str

How to treat the system clock. Use “truncate” (default) to truncate the data file when the system clock drops to zero, and use “ignore” to ignore the system clock (e.g., if head positions are measured multiple times during a recording).

preload : bool 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).

verbose : bool, str, int, or None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more).


raw : instance of RawCTF

The raw data.
