Reconstruct a frame from an FDS manifest and physical sources

Usage

frame_from_fds_manifest(manifest, bindings)

Arguments

manifest: A valid FDS v1 frame manifest.
bindings: Named physical array payloads or array_source descriptors, one per manifest array declaration.

Value

An fmri_frame whose semantic state comes from manifest and whose lazy arrays come from bindings.

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
)
manifest <- fds_frame_manifest(frame)
bindings <- fds_frame_bindings(frame)
rebuilt <- frame_from_fds_manifest(manifest, bindings)
identical(feature_ids(rebuilt), feature_ids(frame))
