wrap_out: Wrap output results

In bbuchsbaum/rMVPA: Multivoxel Pattern Analysis in R

Wrap output results

Description

This function wraps the output results of the performance matrix into a list of spatial objects (NeuroVol or NeuroSurface) for each column in the performance matrix, and structures it as a searchlight_result.

Usage

wrap_out(perf_mat, dataset, ids = NULL)

Arguments

perf_mat	A performance matrix (voxels/vertices x metrics) containing classifier results.
dataset	A dataset object containing the dataset information (including mask and type).
ids	An integer vector of voxel/vertex indices corresponding to the rows of 'perf_mat'. These are typically global indices into the mask space for volumetric data, or vertex numbers for surface data.

Value

A 'searchlight_result' object containing

• 'results': Named spatial maps for each metric.

• 'n_voxels': Total number of voxels/vertices defined by the mask.

• 'active_voxels': Number of voxels/vertices with results.

• 'metrics': Character vector of metric names.
