Release notes

BrainIAK 0.6 (2017-11-10)

Features

  • reprsimil: Add Group Bayesian RSA, add transform (decoding) and score (model selection) functions, add automatic determination of the number of necessary nuisance regressors. utils: modified gen_design to make the generated design matrix approximately scaled in amplitudes. (#194)
  • searchlight: Improved performance via tweaked multiprocessing usage. (#240)
  • fmrisim: Updated drift calculation and masking. (#244)
  • eventseg: Add set_event_patterns() and notebook example (#266)
  • Added a Docker image for testing BrainIAK without installing. (#272)
  • eventseg: Fixed numerical instability bug, added utility function for weighted variance (#292)
  • Restricted multiprocessing to the available number of CPUs. (#293)

Bugfixes

  • searchlight: Do not use sys.exit. (#156)
  • reprsimil: Follow random number guidelines. (#239)
