BUG

  • mne.time_frequency.compute_raw_psd, mne.time_frequency.compute_epochs_psd, mne.time_frequency.psd_multitaper, and mne.time_frequency.psd_welch no longer remove rows/columns of the SSP matrix before applying SSP projectors when picks are provided by `Chris Holdgraf`_.
  • :func:`mne.Epochs.plot_psd` no longer calls a Welch PSD, and instead uses a Multitaper method which is more appropriate for epochs. Flags for this function are passed to mne.time_frequency.psd_multitaper by `Chris Holdgraf`_
  • Time-cropping functions (e.g., :func:`mne.Epochs.crop`, :func:`mne.Evoked.crop`, :func:`mne.io.Raw.crop`, :func:`mne.SourceEstimate.crop`) made consistent with behavior of tmin and tmax of :class:`mne.Epochs`, where nearest sample is kept. For example, for MGH data acquired with sfreq=600.614990234, constructing Epochs(..., tmin=-1, tmax=1) has bounds +/-1.00064103, and now epochs.crop(-1, 1) will also have these bounds (previously they would have been +/-0.99897607). Time cropping functions also no longer use relative tolerances when determining the boundaries. These changes have minor effects on functions that use cropping under the hood, such as :func:`mne.compute_covariance` and mne.connectivity.spectral_connectivity. Changes by `Jaakko Leppakangas`_ and `Eric Larson`_

  • Fix bug where :func:`mne.preprocessing.maxwell_filter` destination parameter did not properly set device-to-head transform by `Eric Larson`_
  • Fix bug in rank calculation of mne.utils.estimate_rank, mne.io.Raw.estimate_rank, and covariance functions where the tolerance was set to slightly too small a value, new 'auto' mode uses values from scipy.linalg.orth by `Eric Larson`_.
  • Fix bug when specifying irregular train_times['slices'] in mne.decoding.GeneralizationAcrossTime, by `Jean-Rémi King`_

  • Fix bug in :func:`mne.merge_events` when using replace_events=False by `Alex Gramfort`_
  • Fix bug in :class:`mne.Evoked` type setting in :func:`mne.stats.linear_regression_raw` by `Eric Larson`_
  • Fix bug in mne.io.edf.RawEDF highpass filter setting to take max highpass to match warning message by `Teon Brooks`_
  • Fix bugs with coordinane frame adjustments in mne.viz.plot_trans by `Eric Larson`_
  • Fix bug in colormap selection in :func:`mne.Evoked.plot_projs_topomap` by `Jaakko Leppakangas`_
  • Fix bug in source normal adjustment that occurred when 1) patch information is available (e.g., when distances have been calculated) and 2) points are excluded from the source space (by inner skull distance) by `Eric Larson`_
  • Fix bug when merging info that has a field with list of dicts by `Jaakko Leppakangas`_
  • The BTi/4D reader now considers user defined channel labels instead of the hard-ware names, however only for channels other than MEG. By `Denis Engemann`_ and `Alex Gramfort`_.
  • The BTi reader :func:`mne.io.read_raw_bti` can now read 2500 system data, by `Eric Larson`_
  • Fix bug in :func:`mne.compute_raw_covariance` where rejection by non-data channels (e.g. EOG) was not done properly by `Eric Larson`_.
  • Change default scoring method of mne.decoding.GeneralizationAcrossTime and mne.decoding.TimeDecoding to estimate the scores within the cross-validation as in scikit-learn_ as opposed to across all cross-validated y_pred. The method can be changed with the score_mode parameter by `Jean-Rémi King`_

API

  • The default picks=None in :func:`mne.viz.plot_epochs_image` now only plots the first 5 channels, not all channels, by `Jona Sassenhagen`_
  • The mesh_color parameter in :func:`mne.viz.plot_dipole_locations` has been removed (use brain_color instead), by `Marijn van Vliet`_
  • Deprecated functions mne.time_frequency.compute_raw_psd and mne.time_frequency.compute_epochs_psd, replaced by mne.time_frequency.psd_welch by `Chris Holdgraf`_
  • Deprecated function mne.time_frequency.multitaper_psd and replaced by mne.time_frequency.psd_multitaper by `Chris Holdgraf`_
  • The y_pred attribute in mne.decoding.GeneralizationAcrossTime and mne.decoding.TimeDecoding is now a numpy array, by `Jean-Rémi King`_
  • The :func:`mne.bem.fit_sphere_to_headshape` function now default to dig_kinds='auto' which will use extra digitization points, falling back to extra plus eeg digitization points if there not enough extra points are available.
  • The :func:`mne.bem.fit_sphere_to_headshape` now has a units argument that should be set explicitly. This will default to units='mm' in 0.12 for backward compatibility but change to units='m' in 0.13.
  • Added default parameters in Epochs class namely event_id=None, tmin=-0.2 and tmax=0.5.
  • To unify and extend the behavior of :func:`mne.compute_raw_covariance` relative to :func:`mne.compute_covariance`, the default parameter tstep=0.2 now discards any epochs at the end of the :class:`mne.io.Raw` instance that are not the full tstep duration. This will slightly change the computation of :func:`mne.compute_raw_covariance`, but should only potentially have a big impact if the :class:`mne.io.Raw` instance is short relative to tstep and the last, too short (now discarded) epoch contained data inconsistent with the epochs that preceded it.
  • The default picks=None in :func:`mne.io.Raw.filter` now picks eeg, meg, seeg, and ecog channels, by `Jean-Rémi King`_ and `Eric Larson`_
  • EOG, ECG and EMG channels are now plotted by default (if present in data) when using :func:`mne.viz.plot_evoked` by `Marijn van Vliet`_
  • Replace pseudoinverse-based solver with much faster Cholesky solver in :func:`mne.stats.linear_regression_raw`, by `Jona Sassenhagen`_.
  • CTF data reader now reads EEG locations from .pos file as HPI points by `Jaakko Leppakangas`_
  • Subselecting channels can now emit a warning if many channels have been subselected from projection vectors. We recommend only computing projection vertors for and applying projectors to channels that will be used in the final analysis. However, after picking a subset of channels, projection vectors can be renormalized with :func:`mne.Info.normalize_proj` if necessary to avoid warnings about subselection. Changes by `Eric Larson`_ and `Alex Gramfort`_.
  • Rename and deprecate mne.Epochs.drop_bad_epochs to :func:`mne.Epochs.drop_bad`, and mne.Epochs.drop_epochs to :func:`mne.Epochs.drop` by `Alex Gramfort`_.
  • The C wrapper mne.do_forward_solution has been deprecated in favor of the native Python version :func:`mne.make_forward_solution` by `Eric Larson`_
  • The events parameter of :func:`mne.EpochsArray` is set by default to chronological time-samples and event values to 1, by `Jean-Rémi King`_
