Previous Versions

v1.2.5 2023-11-29

MEDUSA Kernel 1.2.5 release. Changelog:

Breaking changes:

  • Parameter standard in function set_standard_montage from meeg.meeg.EEGChannelSet

v1.1.3 2022-12-09

MEDUSA Kernel 1.1.3 release. Changelog:

Breaking changes:

  • The spectral analysis, nonlinear analysis and connectivity analysis functions (both phase and amplitude based) support as input signals with dimensions [n_epochs, n_samples, n_channels].
  • Update of Motor Imagery module: Changes in the MIData class.
  • Update in Neurofeedback module: Now includes pipelines for real-time functional connectivity calculation.
  • Laplacian surface filter update: Improved filter design in automatic mode.


Major changes:

  • The algorithms of the nonlinear analysis and connectivity analysis functions have been optimized and calculations are now faster.


Minor changes:

  • Legacy package medusa.bci.remote has been eliminated
  • Tensorflow versions fixed to avoid problems: tensorflow==2.11; tensorflow-probability==0.16
