mne.decoding.compute_ems(epochs, conditions=None, picks=None, n_jobs=1, cv=None, verbose=None)[source]¶ Compute event-matched spatial filter on epochs.
This version of EMS 1 operates on the entire time course. No time window needs to be specified. The result is a spatial filter at each time point and a corresponding time course. Intuitively, the result gives the similarity between the filter at each time point and the data vector (sensors) at that time point.
- Parameters
- epochsinstance of
mne.Epochs The epochs.
- conditions
listofstr|None, defaultNone If a list of strings, strings must match the epochs.event_id’s key as well as the number of conditions supported by the objective_function. If None keys in epochs.event_id are used.
- picks
str|list|slice|None Channels to include. Slices and lists of integers will be interpreted as channel indices. In lists, channel type strings (e.g.,
['meg', 'eeg']) will pick channels of those types, channel name strings (e.g.,['MEG0111', 'MEG2623']will pick the given channels. Can also be the string values “all” to pick all channels, or “data” to pick data channels. None (default) will pick good data channels. Note that channels ininfo['bads']will be included if their names or indices are explicitly provided.- n_jobs
int The number of jobs to run in parallel (default 1). Requires the joblib package.
- cvcross-validation object |
str|None, defaultLeaveOneOut The cross-validation scheme.
- verbosebool,
str,int, orNone If not None, override default verbose level (see
mne.verbose()and Logging documentation for more). If used, it should be passed as a keyword-argument only.
