[Neuroimaging] [ANN] MNE-Python 0.21

[Alexandre Gramfort]

Hello everyone,


We are very pleased to announce the new 0.21 release of MNE-Python!



A few highlights

============


Visualization

   -

   Mixed and volume source estimates can now be visualized in 3D with
   volumetric rendering.
   -

   Added support for plotting cortex “flat maps”.
   -

   3D rendering in Jupyter notebooks thanks to a new backend.
   -

   PyVista is now the default 3D backend. Mayavi is no longer required
   (except for coregistration).
   -

   Added support for plotting of covariance topomaps.
   -

   Improvements to 3D dipole plotting with MRI overlay.


Preprocessing

   -

   Added support for eSSS.
   -

   Automated muscle artifact detection.
   -

   ICA.find_bads_ecg() can now automatically determine the threshold for
   the CTPS method.


EEG

   -

   Added support for the Reference Electrode Standardization Technique
   (REST) infinity reference.


fNIRS

   -

   Various improvements to visualization and processing of fNIRS data.


Data reading

   -

   The new function mne.io.read_raw() automatically selects to correct
   reader based on the provided filename
   -

   Support reading of Persyst data format
   -

   Support reading of Nihon Kohden data format
   -

   Support reading of SNIRF data format


Notable API changes

================

   -

   The function mne.preprocessing.mark_flat has been deprecated in favor of
   mne.preprocessing.annotate_flat() to increase API consistency: we now have
   annotate_flat(), annotate_movement(), and annotate_muscle_zscore().
   -

   The default argument meg=True in mne.pick_types() will change to
   meg=False in version 0.22. Please be sure to update your code.


Python 3.6+ is now required

=====================

This release drops support for Python versions before 3.6. Python 3.6 was
released almost 4 years ago, and removing support for earlier versions
allows us to take advantage of some new, helpful language features.

Installing the new release

===================


Since quite a few things – including dependencies – have changed, we
recommend creating a new environment with a “fresh” installation. Please
follow the installation instructions on our website:
