mne.chpi.compute_head_pos#
- mne.chpi.compute_head_pos(info, chpi_locs, dist_limit=0.005, gof_limit=0.98, adjust_dig=False, verbose=None)[source]#
Compute time-varying head positions.
- Parameters:
- info
mne.Info
The
mne.Info
object with information about the sensors and methods of measurement.- chpi_locs
dict
The time-varying cHPI coils locations, with entries “times”, “rrs”, “moments”, and “gofs”. Typically obtained by
compute_chpi_locs()
orextract_chpi_locs_ctf()
.- dist_limit
float
Minimum distance (m) to accept for coil position fitting.
- gof_limit
float
Minimum goodness of fit to accept for each coil.
- adjust_dig
bool
If True, adjust the digitization locations used for fitting based on the positions localized at the start of the file.
- 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.
- info
- Returns:
- quats
ndarray
, shape (n_pos, 10) The
[t, q1, q2, q3, x, y, z, gof, err, v]
for each fit.
- quats
Notes
New in version 0.20.
