Choose or (temporarily) use the CRANT autosegmentation

Usage

choose_crant(set = TRUE)

with_crant(expr)

Arguments

set: Whether or not to permanently set the CRANT auto-segmentation as the default for fafbseg functions.
expr: An expression to evaluate while CRANT is the default autosegmentation

Value

If set=TRUE a list containing the previous values of the relevant global options (in the style of options. If set=FALSE a named list containing the option values.

Details

bancr inherits a significant amount of infrastructure from the fafbseg package. This has the concept of the active autosegmentation, which in turn defines one or more R options containing URLs pointing to voxel-wise segmentation, mesh etc data. These are normally contained within a single neuroglancer URL which points to multiple data layers. For banc this is the neuroglancer scene returned by crant_scene.

Examples

if (FALSE) { # \dontrun{
choose_crant()
options()[grep("^fafbseg.*url", names(options()))]
} # }
if (FALSE) { # \dontrun{
with_crant(fafbseg::flywire_islatest('576460752653449509'))
} # }
if (FALSE) { # \dontrun{
with_crant(fafbseg::flywire_latestid('576460752653449509'))
} # }
