Check if a bodyid still exists in the specified DVID node

Usage

manc_islatest(
  ids,
  node = "neutu",
  method = c("auto", "size", "sparsevol"),
  ...
)

Arguments

ids: A set of body ids in any form understandable to manc_ids
node: A DVID node (defaults to the current neutu node, see manc_dvid_node)
method: Which DVID endpoint to use. Expert use only.
...: Additional arguments passed to pbsapply and then eventually to httr::HEAD

Value

A logical vector indicating if the body exists (TRUE) or not (FALSE).

Details

Note that the raw speed of this call is still quite slow (typically 5-30 bodies per second from Cambridge). When more than one body id is provided this actually uses manc_size to check if the body has >0 voxels. This is a somewhat expensive operation on the server but can be accept multiple ids. As a further speed-up, when many ids are requested and method="auto" (the recommended default) then the DVID status of bodies is checked. In theory only valid bodies should have such a status (see Slack message).
