2024crant collects together R scripts and functions to work with the clonal raider ant brain (CRANTb) dataset. See https://github.com/flyconnectome/crantr for more details.
Here is an R example of fishing upstream of a single Olfactory Projection Neuron (PN) to find its olfactory receptor input neurons (ORNs) and then going downstream from the ORNs to find the other PNs in the glomerulus. It seems that ther are at least 3 in this case.
library(dplyr)
source("R/crant-funs.R")
crant_partner_summary()
# PN defining a glomerulus
# make sure id is up to date
g1=crantr::crant_latestid("576460752752912786")
# find all the inputs onto this neuron
g1.in=crant_partner_summary(g1, partners = 'i')
# copy/paste ids to neuroglancer, review them and pick out ORNs
g1.in %>% filter(weight>2) %>% with(clipr::write_clip(pre_id))
g1.orns <- fafbseg::flywire_ids('576460752719726635, 576460752719881771, 576460752720182571, 576460752736400683, 576460752736409899')
# Find ORN outputs,
g1.orns.o=crant_partner_summary(g1.orns, partners = 'o')
# review those, copy/paste ids to neuroglancer and then pick out additional PNs
g1.orns.o %>%
filter(weight>5) %>%
with(clipr::write_clip(post_id))
