Flexible specification of manc body ids

manc_ids provides a convenient way to extract body ids from a variety of objects as well as allowing text searches against type/instance information defined in neuprint.

Usage

manc_ids(
  x,
  mustWork = TRUE,
  as_character = TRUE,
  integer64 = FALSE,
  unique = TRUE,
  conn = manc_neuprint(),
  ...
)

Arguments

x

A vector of body ids, data.frame (containing a bodyid column) or a neuroglancer URL.

mustWork

Whether to insist that at least one valid id is returned (default TRUE)

as_character

Whether to return segments as character rather than numeric vector (the default is character for safety).

integer64

whether to return ids with class bit64::integer64.

unique

Whether to ensure that only unique ids are returned (default TRUE)

conn

optional, a neuprintr connection object, which also specifies the neuPrint server. If NULL, the defaults set in your .Rprofile or .Renviron are used. See neuprint_login for details.

...

Additional arguments passed to neuprint_search

Examples

# \donttest{
# search by type
manc_ids("DNp01")
#> Error in neuprint_login(server = server, dataset = dataset, token = token,     ...): Sorry you must specify a neuprint server! See ?neuprint_login for details!
# You can also do more complex queries using regular expressions
# introduced by a slash and specifying the field to be searched
dns=manc_ids("/type:DN.+")
#> Error in neuprint_login(server = server, dataset = dataset, token = token,     ...): Sorry you must specify a neuprint server! See ?neuprint_login for details!

# you can also use Neo4J cypher queries by using the where: prefix
# note that each field of the neuron must prefixed with "n."
bignogroupids <-
  manc_ids("where:NOT exists(n.group) AND n.synweight>5000 AND n.class CONTAINS 'neuron'")
#> Error in neuprint_login(server = server, dataset = dataset, token = token,     ...): Sorry you must specify a neuprint server! See ?neuprint_login for details!
if (FALSE) { # \dontrun{
# Finally you can use the same queries wherever you specify body ids
# NB if you want to be sure that regular neuprintr functions target
# the VNC dataset, use conn=manc_neuprint()
lrpairs.meta=neuprintr::neuprint_get_meta("/name:[0-9]{5,}_[LR]", conn=manc_neuprint())
} # }
# }
