mvpa2.datasets.mri.BoxcarMapper

Inheritance diagram of BoxcarMapper

class mvpa2.datasets.mri.BoxcarMapper(startpoints, boxlength, offset=0, **kwargs)

Mapper to combine multiple samples into a single sample.

Notes

This mapper is somewhat unconventional since it doesn’t preserve number of samples (ie the size of 0-th dimension).

Available conditional attributes:

  • calling_time+: Time (in seconds) it took to call the node
  • raw_results: Computed results before invoking postproc. Stored only if postproc is not None.
  • training_time+: Time (in seconds) it took to train the learner

(Conditional attributes enabled by default suffixed with +)

Parameters :

startpoints : sequence

Index values along the first axis of ‘data’.

boxlength : int

The number of elements after ‘startpoint’ along the first axis of ‘data’ to be considered for the boxcar.

offset : int

The offset between the provided starting point and the actual start of the boxcar.

enable_ca : None or list of str

Names of the conditional attributes which should be enabled in addition to the default ones

disable_ca : None or list of str

Names of the conditional attributes which should be disabled

auto_train : bool

Flag whether the learner will automatically train itself on the input dataset when called untrained.

force_train : bool

Flag whether the learner will enforce training on the input dataset upon every call.

space: str, optional :

Name of the ‘processing space’. The actual meaning of this argument heavily depends on the sub-class implementation. In general, this is a trigger that tells the node to compute and store information about the input data that is “interesting” in the context of the corresponding processing in the output dataset.

postproc : Node instance, optional

Node to perform post-processing of results. This node is applied in __call__() to perform a final processing step on the to be result dataset. If None, nothing is done.

descr : str

Description of the instance

forward1(data)
reverse1(data)
