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,
...
)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.
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.
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.
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.
if TRUE, meta data for found bodyids is also pulled
if TRUE, all bodies are considered, if FALSE, only 'Neurons', i.e. bodies with a status roughly traced status.
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.
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
A set of bodyids or a query
Whether to insist that at least one valid id is returned
(default TRUE)
Whether to ensure that only unique ids are returned (default
TRUE)
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).
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.
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
