mne.chpi.extract_chpi_locs_ctf#
- mne.chpi.extract_chpi_locs_ctf(raw, verbose=None)[source]#
Extract cHPI locations from CTF data.
- Parameters:
- rawinstance of
Raw
Raw data with CTF cHPI information.
- verbose
bool
|str
|int
|None
Control verbosity of the logging output. If
None
, use the default verbosity level. See the logging documentation andmne.verbose()
for details. Should only be passed as a keyword argument.

- Returns:
- chpi_locs
dict
The time-varying cHPI coils locations, with entries “times”, “rrs”, “moments”, and “gofs”.
- chpi_locs
Notes
CTF continuous head monitoring stores the x,y,z location (m) of each chpi coil as separate channels in the dataset:
HLC001[123]\\*
- nasionHLC002[123]\\*
- lpaHLC003[123]\\*
- rpa
This extracts these positions for use with
compute_head_pos()
.New in version 0.20.
