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.
dict
The time-varying cHPI coils locations, with entries “times”, “rrs”, “moments”, and “gofs”.
Notes
CTF continuous head monitoring stores the x,y,z location (m) of each chpi coil as separate channels in the dataset:
HLC001[123]\\*
- nasion
HLC002[123]\\*
- lpa
HLC003[123]\\*
- rpa
This extracts these positions for use with
compute_head_pos()
.
New in version 0.20.
