Version 1.10.0.dev74+gb6cd5f4e5 (development) (2025-03-23)

Bugfixes

• Fix bug where mne.export.export_raw() does not correct for recording start time (raw.first_time) when exporting Raw instances to EDF or EEGLAB formats, by Qian Chu. (#12656)

• Fixed behavior of mne.viz.plot_source_estimates() where the title was not displayed properly, by new contributor Shristi Baral. (#12828)

• Fix epoch indexing in mne.time_frequency.EpochsTFRArray when initialising the class with the default drop_log parameter, by Thomas Binns. (#13028)

• Fix loading and saving of EpochsSpectrum objects that contain slash-separators in their condition names, by Daniel McCloy. (#13042)

• Fix input boxes for the max value not showing when plotting fieldlines with plot_evoked_field() when show_density=False, by Marijn van Vliet. (#13048)

• Fix bug with saving of anonymized data when helium info is present in measurement info, by Eric Larson. (#13056)

• Fix computation of time intervals in mne.preprocessing.compute_fine_calibration() by Eric Larson. (#13062)

• Fix bug in the colorbars created by mne.viz.plot_evoked_topomap() by Santeri Ruuskanen. (#13063)

• Improved sklearn class compatibility and compliance, which resulted in some parameters of classes having an underscore appended to their name during fit, such as:

  • mne.decoding.FilterEstimator parameter picks passed to the initializer is set as est.picks_

  • mne.decoding.UnsupervisedSpatialFilter parameter estimator passed to the initializer is set as est.estimator_

  Unused verbose class parameters (that had no effect) were removed from PSDEstimator, TemporalFilter, and FilterEstimator as well. Changes by Eric Larson. (#13065)

• Fix bug where taper weights were not correctly applied when computing multitaper power with mne.Epochs.compute_tfr() and mne.time_frequency.tfr_array_multitaper(), by Thomas Binns. (#13067)

• Fix bug cause by unnecessary assertion when loading mixed frequency EDFs without preloading mne.io.read_raw_edf() by Simon Kern. (#13069)

• Return events when requested even when current matches the desired sfreq in mne.io.Raw.resample() by new contributor Roy Eric Wieske. (#13070)

• Fix bug with automated Mesa 3D detection for proper 3D option setting on systems with software rendering, by Eric Larson. (#13082)

• Fix bug with reading digitization points from digitization strings with newer MEGIN systems, by Eric Larson. (#13083)

• Fix bug when loading certain EEGLAB files that do not contain a nodatchans field, by Clemens Brunner. (#13097)

• Do not convert the first “New Segment” marker in a BrainVision file to an annotation, as it only contains the recording date (which is already available in info["meas_date"]), by Clemens Brunner. (#13100)

• Take units (m or mm) into account when drawing plot_evoked_field() on top of Brain, by Marijn van Vliet. (#13101)

• Fix bug in mne.io.read_raw_gdf(), by new contributor Rongfei Jin. (#13113)

• Fixed CTF cHPI coil location detection in mne.chpi.extract_chpi_locs_ctf() by new contributor Shresth Keshari. (#13123)

• Improved the handling of problematic MFF files in mne.io.read_raw_egi by Scott Huberty. (#13145)

API changes by deprecation

• The backward-compatible defaults in mne.preprocessing.maxwell_filter() of st_overlap=False and `mc_interp=None will change to their smooth variants True and "hann", respectively, in 1.11, by Eric Larson. (#13080)

New features

• Add new select parameter to mne.viz.plot_evoked_topo() and mne.Evoked.plot_topo() to toggle lasso selection of sensors, by Marijn van Vliet. (#12071)

• Added the option to return taper weights from mne.time_frequency.tfr_array_multitaper(), and taper weights are now stored in the mne.time_frequency.BaseTFR objects, by Thomas Binns. (#12910)

• Add fig.mne container for Colorbar in plot_connectivity_circle to allow users to access it directly, by Santeri Ruuskanen. (#13019)

• Add PCA-OBS preprocessing for the removal of heart-artefacts from EEG or ESG datasets via mne.preprocessing.apply_pca_obs(), by new contributor Emma Bailey and new contributor Steinn Hauser Magnusson. (#13037)

• Add mne.Evoked.interpolate_to() to allow interpolating EEG data to other montages, by new contributor Antoine Collas. (#13044)

• Added mne.time_frequency.combine_tfr() to allow combining TFRs across tapers, by Thomas Binns. (#13054)

• Add the function mne.time_frequency.combine_spectrum() for combining data across mne.time_frequency.Spectrum objects, and allow mne.grand_average() to operate on mne.time_frequency.Spectrum objects, by Thomas Binns. (#13058)

• Add smooth processing of tSSS windows (using overlap-add) and movement compensation (using smooth interpolation of head positions) in mne.preprocessing.maxwell_filter() via st_overlap and `mc_interp options, respectively, by Eric Larson. (#13080)

• The mne.Info.save() method now has an overwrite and a verbose parameter, by Stefan Appelhoff. (#13107)
