It lets you:

• switch between atlases
• slice through 3D volumes
• show and hide glomeruli
• see glomerulus names, receptors, and sensilla
• compare reference maps and tables from different sources

Reference Table

The reference table is a cross-dataset index for glomeruli, receptors, sensilla, ligands, valence, driver lines, VFB IDs, and atlas coverage.

This preview shows selected columns only; it is not the full table schema.

Glomerulus	Receptors	Sensillum	Key ligand	Valence	Receptor lines	Projection lines
D	Or69aA, Or69aB	Ab9A	linalool	aversive	Orco-GAL4; Orco-T2A-QF2; Ir8a-T2A-QF2	GH146-GAL4; ChAT-GAL4
DA1	Or67d	At1A	cis-vaccenyl acetate	mating/aggression	Orco-GAL4; Orco-T2A-QF2; Ir76b-T2A-QF2; Ir25a-T2A-QF2	GH146-GAL4; ChAT-GAL4
DA2	Or56a, Or33a	Ab4B	geosmin	aversive	Orco-GAL4; Orco-T2A-QF2; Ir25a-T2A-QF2	GH146-GAL4; ChAT-GAL4

Available columns: canonical_glomerulus, receptor_consensus, receptor_benton_2025, receptor_potter_task_2022, receptor_odour_scenes, receptor_door, sensillum_consensus, sensory_organ_consensus, sensillum_benton_2025, sensory_organ_benton_2025, sensillum_potter_task_2022, sensillum_odour_scenes, sensillum_door, sensory_organ_door, neuron_name_benton_2025, essential_coreceptor_benton_2025, co_receptor_door, orco_gal4_grabe_2015, orco_t2a_qf2, ir8a_t2a_qf2, ir76b_t2a_qf2, ir25a_t2a_qf2, key_agonists_benton_2025, sensory_scene_benton_2025, key_ligand, odour_scene, valence, fbbt_id, vfb_name, vfb_synonyms, projection_neuron_lines, projection_neuron_line_source, gh146_gal4, gh146_pn_female, gh146_pn_male, chat_gal4, chat_soma_count, chat_adpn, chat_lpn, chat_vpn, sensory_neuron_lines, present_grabe_2015, present_hemibrain, present_flywire, present_door_map, present_door_mappings, present_potter_task_2022, present_benton_2025, present_bates_schlegel_2020.

Requirements

• uv
• A desktop environment that can open napari / Qt windows

Python and package dependencies are managed by uv from pyproject.toml.

Start

From PyPI:

pip install lobemap
lobemap

From a source checkout:

uv sync
./lobemap

Choose an atlas from the dropdown in napari.

You can also open one atlas directly:

./lobemap --atlas flywire

Generated Data

Some viewers use derived cache files under data/derived/ for fast startup and slicing. These generated files are tracked so a fresh checkout can open the viewer without rebuilding caches. The PyPI package includes runtime source tables/volumes plus tracked data/derived/ and data/validation/ caches needed by the installed viewer. Rebuild all generated visual data after source-data changes with:

uv run python scripts/regenerate_visual_data.py

The rebuild script uses the tracked source files and needs pdftoppm to render the Potter Task 2022 PDF preview.

What Is Included

• 3D atlas viewers for Grabe 2015, Bates Schlegel 2020, hemibrain, FlyWire, JRC2018Unisex, and Benton 2025
• 2D reference viewers for DoOR and Potter Task 2022
• Virtual Fly Brain and BANC resource lookup
• reference tables for glomerulus names, receptors, sensilla, and direct line labels
