neuprint_search searches for bodyids corresponding to a given name. By default performs regex sensitive matches against neuron names and returns a data.frame.

neuprint_ids provides for flexible search / specification of neuprint body ids. Use it at the start of any function that accepts body ids. Queries are by default partial and fixed (i.e. non-regex) against type. Returns a character vector of bodyids.

neuprint_search(
  search,
  field = "name",
  fixed = FALSE,
  exact = NULL,
  meta = TRUE,
  all_segments = FALSE,
  dataset = NULL,
  conn = NULL,
  ...
)

neuprint_ids(
  x,
  mustWork = TRUE,
  unique = TRUE,
  fixed = TRUE,
  conn = NULL,
  dataset = NULL,
  ...
)

Arguments

search

Search query, by default a regular expression that must match the whole of the neuPrint instance name field. See examples and the field, fixed and exact for how this can be modified.

field

the meta data field in which you want a match for your search query. Defaults to name (or instance, as handled by neuprintr:::neuprint_name_field). Other common options include type, status, cellBodyFiber etc.

fixed

if FALSE (the default), search is interpreted as a regular expression (i.e. "Advanced input" in neuPrint Explorer). If TRUE, the string search is interpreted as a simple character string to be matched (the default search behavior in neuPrint explorer). In this case partial matches are fine.

exact

Whether the query must match the whole field. This is always true for regular expression queries while the default (NULL) implies false for fixed queries.

meta

if TRUE, meta data for found bodyids is also pulled

all_segments

if TRUE, all bodies are considered, if FALSE, only 'Neurons', i.e. bodies with a status roughly traced status.

dataset

optional, a dataset you want to query. If NULL, the default specified by your R environ file is used or, failing that the current connection, is used. See neuprint_login for details.

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

x

A set of bodyids or a query

mustWork

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

unique

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

Value

a vector of body ids, or a data frame with their meta information

For neuprint_ids, a character vector of bodyids (of length 0 when there are none and mustWork=FALSE).

Standard query syntax

It is probably best just to look at the examples, but the query syntax is as follows where square brackets denote optional parts:

[!/][<field>:]<query>

Starting with the optional leading character. An exclamation mark denotes an exact, fixed search. The / denotes a regular expression (exact) search. When both are missing, a partial, fixed search is carried out.

The optional field argument terminated by a colon defines a field other than the default one to use for the query.

Finally the query itself is a plain text (fixed) or regular expression query.

Extended query syntax

As a stepping stone to writing full CYPHER queries against Neo4J you can used the special where keyword to introduce your queries:

where:<cypher query>

e.g.

"where:exists(n.somaLocation) AND n.post>30000 AND NOT n.cropped"

Note that properties of individual nodes (i.e. neurons) must be prefixed with n. as would be typical in a CYPHER query. This feature is still experimental and details of the interface may still change. If you have feedback please do so at https://github.com/natverse/neuprintr/pull/153.
