Resolve Indices from Series Selector

Source: R/all_generic.R
resolve_indices.Rd

Converts a series selector specification into actual voxel indices within the dataset mask.

Usage

resolve_indices(selector, dataset, ...)

Arguments

selector

A series selector object (e.g., index_selector, voxel_selector)

dataset

An fMRI dataset object providing spatial context

...

Additional arguments passed to methods

Value

Integer vector of indices into the masked data

Details

Series selectors provide various ways to specify spatial subsets of fMRI data. This generic function resolves these specifications into actual indices that can be used to extract data. Different selector types support different selection methods:

  • index_selector: Direct indices into masked data

  • voxel_selector: 3D coordinates

  • roi_selector: Region of interest masks

  • sphere_selector: Spherical regions

series_selector for selector types, fmri_series for using selectors to extract data

Examples

# \donttest{
# Example with index selector
sel <- index_selector(1:10)
# indices <- resolve_indices(sel, dataset)

# Example with voxel coordinates
sel <- voxel_selector(cbind(x = 10, y = 20, z = 15))
# indices <- resolve_indices(sel, dataset)
# }
