New in 0.32

  • Requires at least Python 3.7

  • API changes:

    • Consistent class names for tests in test, testnd and pipeline.

    • When using a basis, the function now considers the effect of the basis when normalizing predictors. This change leads to slightly different results, so TRFs should not be compared between this and previous versions. To facilitate keeping track of this change, it corresponds to a change in the BoostingResult.algorithm_version attribute from -1 to 0.

    • A custom baseline period for epochs can now be specified as a parameter in the epoch definition (e.g., 'baseline': (-0.2, -0.1)). When loading data, specifying baseline=True uses the epoch’s custom baseline.

New in 0.11

  • MneExperiment:

    • Change in the way the covariance matrix is defined: The epoch for the covariance matrix should be specified in MneExperiment.epochs['cov']. The regularization is no longer part of set_inv(), but is instead set with MneExperiment.set(cov='reg') or MneExperiment.set(cov='noreg').
