* master:
  make the test less sensitive to numerical errors
  Fixing typos.
  Cleanup
  simplify using genfromtxt
  Make it more general - calculate moments.
  Added skewness calculation.
  enh: updated openfmri workflow example to work with current directory and fileformat structure and to register copes and varcopes to mni space
  enh: added transformation of individual copes and varcopes to standard space via anatomical image
  fix output listing
  Add deprecation for old output variable modulated_input_image in Segment (to be replaced with bias_corrected_image) and removed exists=True for outputs that are predicated on input settings
  In Segment, include bias-corrected output only if corresponding save_bias_corrected boolean is True. This prevents to throw an error when save_bias_corrected is set to False but Segment still looks for a created bias-corrected output.
  Segment in SPM interface throws error.
  rf: refactored automatic file name generation in base class
  fix: outputs never sets outfile if defined.
  Make WarpTimeSeriesImageMultiTransform not crash due to wrong return code.
  Added support for non standard return codes. For example when a non zero code is returned but the program has run successfully.
  fix for the which[0]=1 option -> reslice 2..n images
