mvpa2.support.nibabel.afni_niml_dset

AFNI NIML dataset I/O support. Usually this type of datasets are used for functional data (timeseries, preprocessed data), statistical maps or searchlight results.

Created on Feb 19, 2012

Files that are read with the afni_niml_dset.read function contain a dict with the following fields:

.data PxN data for P nodes and N columns (values per node). .node_indices P indices of P nodes that data refers to (base 0) .history String with history information .stats list with statistical information for each column. .labels list with labels of the data columns .dset_type String with the data set type

Similarly, such a dict can be saved to a .niml.dset file using the afni_niml_dset.write function
