API

• Deprecated separate reading of annotations and synthesis of STI014 channels in readers by Joan Massich:

  • Deprecated mne.io.read_annotations_eeglab

  • Deprecated annot and annotmap parameters in read_raw_edf()

  • Deprecated stim_channel parameters in read_raw_edf(), read_raw_brainvision(), and read_raw_eeglab()

  Annotations are now added to raw instances directly upon reading as raw.annotations. They can also be read separately with mne.read_annotations() for EEGLAB, BrainVision, EDF, and Brainstorm formats. Use mne.events_from_annotations(raw.annotations) to convert these to events instead of the old way (using STI014 channel synthesis followed by mne.find_events(raw)).

  In 0.17 (this release)

  Use read_raw_...(stim_channel=False) to disable warnings (and stim channel synthesis), but other arguments for stim_channel will still be supported.

  In 0.18

  The only supported option will be read_raw_...(stim_channel=False), and all stim-channel-synthesis arguments will be removed. At this point, stim_channel should be removed from scripts for future compatibility, but stim_channel=False will still be acceptable for backward compatibility.

  In 0.19

  The stim_channel keyword arguments will be removed from read_raw_... functions.

• Fixed a bug where selecting epochs using hierarchical event IDs (HIDs) was and-like instead of or-like.

This is now consistent with how epoch selection was done without HID tags, e.g. epochs[['a', 'b']] would select all epochs of type 'a' and type 'b'. By Eric Larson

• Weakest filter is now used for heterogeneous channel filter settings, leading to more consistent behavior with filtering methods applied to a subset of channels (e.g. Raw.filter with picks != None).

• Fixed plotting and timing of Annotations and restricted addition of annotations outside data range to prevent problems with cropping and concatenating data by Jaakko Leppakangas

• Fixed ICA plotting functions to refer to IC index instead of component number by Andreas Hojlund and Jaakko Leppakangas

• Fixed bug in padding of Stockwell transform for signal of length a power of 2 by Johannes Niediek

API

• The add_eeg_ref argument in core functions like mne.io.read_raw_fif() and mne.Epochs has been deprecated in favor of using mne.set_eeg_reference() and equivalent instance methods like raw.set_eeg_reference(). In functions like mne.io.read_raw_fif() where the default in 0.13 and older versions is add_eeg_ref=True, the default will change to add_eeg_ref=False in 0.14, and the argument will be removed in 0.15.

• Multiple aspects of FIR filtering in MNE-Python has been refactored:

  1. New recommended defaults for l_trans_bandwidth='auto', h_trans_bandwidth='auto', and filter_length='auto'. This should generally reduce filter artifacts at the expense of slight decrease in effective filter stop-band attenuation. For details see Defaults in MNE-Python. The default values of l_trans_bandwidth=h_trans_bandwidth=0.5 and filter_length='10s' will change to 'auto' in 0.14.

  2. The filter_length=None option (i.e. use len(x)) has been deprecated.

  3. An improved phase='zero' zero-phase FIR filtering has been added. Instead of running the designed filter forward and backward, the filter is applied once and we compensate for the linear phase of the filter. The previous phase='zero-double' default will change to phase='zero' in 0.14.

  4. A warning is provided when the filter is longer than the signal of interest, as this is unlikely to produce desired results.

  5. Previously, if the filter was as long or longer than the signal of interest, direct FFT-based computations were used. Now a single code path (overlap-add filtering) is used for all FIR filters. This could cause minor changes in how short signals are filtered.

• Support for Python 2.6 has been dropped, and the minimum supported dependencies are NumPy 1.8, SciPy 0.12, and Matplotlib 1.3 by Eric Larson

• When CTF gradient compensation is applied to raw data, it is no longer reverted on save of mne.io.Raw.save() by Eric Larson

• Now it is possible to plot only a subselection of channels in mne.viz.plot_raw() by using an array for order parameter by Jaakko Leppakangas

• EOG channels can now be included when calling mne.preprocessing.ICA.fit() and a proper error is raised when trying to include unsupported channels by Alexander Rudiuk

• mne.concatenate_epochs() and mne.compute_covariance() now check to see if all Epochs instances have the same MEG-to-Head transformation, and errors by default if they do not by Eric Larson

• Added option to pass a list of axes to mne.viz.plot_epochs_image() by Mikołaj Magnuski

• Constructing IIR filters in mne.filter.construct_iir_filter() defaults to output='ba' in 0.13 but this will be changed to output='sos' by Eric Larson

• Add zorder parameter to mne.Evoked.plot() and derived functions to sort allow sorting channels by e.g. standard deviation, by Jona Sassenhagen

• The baseline parameter of mne.Epochs.apply_baseline() is set by default (None, 0), by Felix Raimundo

• Adds mne.Evoked.apply_baseline() to be consistent with mne.Epochs.apply_baseline(), by Felix Raimundo

• Deprecated the baseline parameter in mne.Evoked, by Felix Raimundo

• The API of mne.SourceEstimate.plot() and mne.viz.plot_source_estimates() has been updated to reflect current PySurfer 0.6 API. The config_opts parameter is now deprecated and will be removed in mne 0.14, and the default representation for time will change from ms to s in mne 0.14. By Christian Brodbeck

• The default dataset location has been changed from examples/ in the MNE-Python root directory to ~/mne_data in the user’s home directory, by Eric Larson

• A new option set_env has been added to mne.set_config() that defaults to False in 0.13 but will change to True in 0.14, by Eric Larson

• The compensation parameter in mne.io.read_raw_fif() has been deprecated in favor of the method mne.io.Raw.apply_gradient_compensation() by Eric Larson

• mne.io.read_raw_eeglab() and mne.read_epochs_eeglab() now take additional argument uint16_codec that allows to define the encoding of character arrays in set file. This helps in rare cases when reading a set file fails with TypeError: buffer is too small for requested array. By Mikołaj Magnuski

• Added mne.decoding.TemporalFilter to filter data in scikit-learn pipelines, by Asish Panda

• mne.preprocessing.create_ecg_epochs() now includes all the channels when picks=None by Jaakko Leppakangas

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.

• 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., mne.Epochs.crop(), mne.Evoked.crop(), mne.io.Raw.crop(), mne.SourceEstimate.crop()) made consistent with behavior of tmin and tmax of 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 mne.compute_covariance() and mne.connectivity.spectral_connectivity.

• Fix bug in colormap selection in 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 mne.io.read_raw_bti() can now read 2500 system data, by Eric Larson

• Fix bug in 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-Remi King

• Fix bug in mne.io.Raw.save() where, in rare cases, automatically split files could end up writing an extra empty file that wouldn’t be read properly by Eric Larson

• Fix :class:mne.realtime.StimServer by removing superfluous argument ip used while initializing the object by Mainak Jas.

• Fix removal of projectors in mne.preprocessing.maxwell_filter() in st_only=True mode by Eric Larson

API

• The default picks=None in mne.viz.plot_epochs_image() now only plots the first 5 channels, not all channels, by Jona Sassenhagen

• The mesh_color parameter in 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

• The y_pred attribute in mne.decoding.GeneralizationAcrossTime and mne.decoding.TimeDecoding is now a numpy array, by Jean-Remi King

• The 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 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 mne.compute_raw_covariance() relative to mne.compute_covariance(), the default parameter tstep=0.2 now discards any epochs at the end of the mne.io.Raw instance that are not the full tstep duration. This will slightly change the computation of mne.compute_raw_covariance(), but should only potentially have a big impact if the 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 mne.io.Raw.filter() now picks eeg, meg, seeg, and ecog channels, by Jean-Remi King and Eric Larson

• EOG, ECG and EMG channels are now plotted by default (if present in data) when using mne.viz.plot_evoked() by Marijn van Vliet

• 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 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 mne.Epochs.drop_bad(), and mne.Epochs.drop_epochs to mne.Epochs.drop() by Alex Gramfort.

• The C wrapper mne.do_forward_solution has been deprecated in favor of the native Python version mne.make_forward_solution() by Eric Larson

• The events parameter of mne.EpochsArray() is set by default to chronological time-samples and event values to 1, by Jean-Remi King
