braindecode.datasets.create_from_mne_raw(raws, trial_start_offset_samples, trial_stop_offset_samples, window_size_samples, window_stride_samples, drop_last_window, descriptions=None, mapping=None, preload=False, drop_bad_windows=True)

Create WindowsDatasets from mne.RawArrays

Parameters
raws: array-like

list of mne.RawArrays

trial_start_offset_samples: int

start offset from original trial onsets in samples

trial_stop_offset_samples: int

stop offset from original trial stop in samples

window_size_samples: int

window size

window_stride_samples: int

stride between windows

drop_last_window: bool

whether or not have a last overlapping window, when windows do not equally divide the continuous signal

descriptions: array-like

list of dicts or pandas.Series with additional information about the raws

mapping: dict(str: int)

mapping from event description to target value

preload: bool

if True, preload the data of the Epochs objects.

drop_bad_windows: bool

If True, call .drop_bad() on the resulting mne.Epochs object. This step allows identifying e.g., windows that fall outside of the continuous recording. It is suggested to run this step here as otherwise the BaseConcatDataset has to be updated as well.

Returns
windows_datasets: BaseConcatDataset

X and y transformed to a dataset format that is compativle with skorch and braindecode
