Extract physical array bindings from a frame

Storage codecs use this helper to pair each source-free FDS array declaration with its current physical or in-memory array_source.

Usage

fds_frame_bindings(x)

Arguments

x

An fmri_frame.

Value

A named list of array_source descriptors keyed exactly like the manifest arrays registry.

Examples

voxels <- volume_space(dim = c(2, 2, 1), affine = diag(4), template = "toy")
frame <- fmri_frame(
  assays = list(bold = matrix(rnorm(3 * n_features(voxels)), nrow = 3)),
  observations = data.frame(.obs_id = paste0("vol-", 1:3)),
  space = voxels
)
bindings <- fds_frame_bindings(frame)
names(bindings)
#> [1] "assays/bold"
