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)
fds_manifest_digest(manifest)
