VFB provides a simple methods for exploring connectomics data
get_connected_neurons_by_type allows queries for connections between defined upstream and downstream neuron types/classes. This supports a level of abstraction not available without VFB, where grouping of neurons by higher level classifications is limited to extraction of classification from standardised names. The following examples take advantage of the abstract clasifications on VFB to explore direct synaptic connections.

More sophisticated connectomics queries require direct queries of connectomics DB APIs
CATMAID connectivity queries
Broadly speaking, using pymaid to query CATMAID servers lets you fetch connectivity data as either lists of up- and downstream partners or as whole adjacency matrices.
These examples use the VFB FAFB server.

neuprint connectivity queries
To programmatically interface with neuprint, we will use neuprint-python (link). It requires an API token which you can get via the website and is bound to the Google account that you use to log into neuprint. For this workshop we provide such a token as environment variable but you will need to start using your own token after the workshop is over.
These examples use the hemibrain v1.1 dataset.
neuprint-python
First we have to initialize the connection.
[20]:
!pip install neuprint-python --quiet
import neuprint as neu
client = neu.Client('https://neuprint.janelia.org',
dataset='hemibrain:v1.2.1',
token='eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6InZmYndvcmtzaG9wLm5ldXJvZmx5MjAyMEBnbWFpbC5jb20iLCJsZXZlbCI6Im5vYXV0aCIsImltYWdlLXVybCI6Imh0dHBzOi8vbGg2Lmdvb2dsZXVzZXJjb250ZW50LmNvbS8tWXFDN21NRXd3TlEvQUFBQUFBQUFBQUkvQUFBQUFBQUFBQUEvQU1adXVjbU5zaXhXZDRhM0VyTTQ0ODBMa2IzNDdvUlpfUS9zOTYtYy9waG90by5qcGc_c3o9NTA_c3o9NTAiLCJleHAiOjE3OTQwOTE4ODd9.ceg4mrj2o-aOhK0NHNGmBacg8R34PBPoLBwhCo4uOCQ')
Most functions in neuprint-python accept neu.NeuronCriteria which is effectively a filter for body IDs, types, cellbody fibers (~lineages), etc:
[21]:
help(neu.NeuronCriteria)
Help on class NeuronCriteria in module neuprint.queries.neuroncriteria:
class NeuronCriteria(builtins.object)
| NeuronCriteria(matchvar='n', *, bodyId=None, type=None, instance=None, regex='guess', status=None, statusLabel=None, rois=None, inputRois=None, outputRois=None, roi_req='all', min_roi_inputs=1, min_roi_outputs=1, group=None, serial=None, cropped=None, birthtime=None, cellBodyFiber=None, class_=None, entryNerve=None, exitNerve=None, hemilineage=None, longTract=None, modality=None, origin=None, predictedNt=None, serialMotif=None, somaNeuromere=None, somaSide=None, subclass=None, synonyms=None, systematicType=None, target=None, label=None, min_pre=0, min_post=0, somaLocation=None, tosomaLocation=None, rootLocation=None, soma=None, client=None)
|
| Neuron selection criteria.
|
| Specifies which fields to filter by when searching for a Neuron (or Segment).
| This class does not send queries itself, but you use it to specify search
| criteria for various query functions.
|
| Note:
| For simple queries involving only particular bodyId(s) or type(s)/instance(s),
| you can usually just pass the ``bodyId`` or ``type`` to the query function,
| without constructing a full ``NeuronCriteria``.
|
| .. code-block:: python
|
| from neuprint import fetch_neurons, NeuronCriteria as NC
|
| # Equivalent
| neuron_df, conn_df = fetch_neurons(NC(bodyId=329566174))
| neuron_df, conn_df = fetch_neurons(329566174)
|
| # Equivalent
| # (Criteria is satisfied if either type or instance matches.)
| neuron_df, conn_df = fetch_neurons(NC(type="OA-VPM3", instance="OA-VPM3"))
| neuron_df, conn_df = fetch_neurons("OA-VPM3")
|
| Methods defined here:
|
| __eq__(self, value)
| Implement comparison between criteria.
| Note: 'matchvar' is not considered during the comparison.
|
| __init__(self, matchvar='n', *, bodyId=None, type=None, instance=None, regex='guess', status=None, statusLabel=None, rois=None, inputRois=None, outputRois=None, roi_req='all', min_roi_inputs=1, min_roi_outputs=1, group=None, serial=None, cropped=None, birthtime=None, cellBodyFiber=None, class_=None, entryNerve=None, exitNerve=None, hemilineage=None, longTract=None, modality=None, origin=None, predictedNt=None, serialMotif=None, somaNeuromere=None, somaSide=None, subclass=None, synonyms=None, systematicType=None, target=None, label=None, min_pre=0, min_post=0, somaLocation=None, tosomaLocation=None, rootLocation=None, soma=None, client=None)
| All criteria must be passed as keyword arguments.
|
| .. note::
| Only ``bodyId``, ``type``, ``instance``, and ROI-related criteria are
| applicable to all datasets. The applicability of all other criteria depends
| on the dataset being accessed (e.g. hemibrain, manc, etc.).
|
| .. note::
|
| **Options for specifying ROI criteria**
|
| The ``rois`` argument merely matches neurons that intersect the given ROIs at all
| (without distinguishing between inputs and outputs).
|
| The ``inputRois`` and ``outputRois`` arguments allow you to put requirements
| on whether or not neurons have inputs or outputs in the listed ROIs.
| It produces a more expensive query, but it's more selective.
| It also enables you to require a minimum number of connections in the given
| ``inputRois`` or ``outputRois`` using the ``min_roi_inputs`` and ``min_roi_outputs``
| criteria.
|
| In either case, use use ``roi_req`` to specify whether a neuron must match just
| one (``any``) of the listed ROIs, or ``all`` of them.
|
| .. note::
|
| **Matching against missing values (NULL)**
|
| To search for neurons which are missing given property entirely,
| you can use a list containing ``None``, or the special value ``neuprint.IsNull``.
| For example, to find neurons with no `type`, use ``type=[None]`` or ``type=IsNull``.
|
| **Matching against any value (NOT NULL)**
|
| To search for any non-null value, you can use ``neuprint.NotNull``. For
| example, to find neurons that have a type (no matter what the
| type is), use ``type=NotNull``.
|
| Args:
| matchvar (str):
| An arbitrary cypher variable name to use when this
| ``NeuronCriteria`` is used to construct cypher queries.
| Must begin with a lowercase letter.
|
| bodyId (int or list of ints):
| List of bodyId values.
|
| type (str or list of str):
| Cell type. Matches depend on the the ``regex`` argument.
| If both ``type`` and ``instance`` criteria are supplied, any neuron that
| matches EITHER criteria will match the overall criteria.
|
| instance (str or list of str):
| Cell instance (specific cell name). Matches depend on the the ``regex`` argument.
| If both ``type`` and ``instance`` criteria are supplied, any neuron that
| matches EITHER criteria will match the overall criteria.
|
| regex (bool):
| If ``True``, the ``instance`` and ``type`` arguments will be interpreted as
| regular expressions, rather than exact match strings.
| If ``False``, only exact matches will be found.
| By default, the matching method will be automatically chosen by inspecting the
| ``type`` and ``instance`` strings. If they contain regex-like characters,
| then we assume you intend regex matching. (You can see which method was chosen by
| checking the ``regex`` field after the ``NeuronCriteria`` is constructed.)
|
| status (str or list of str):
| Indicates the status of the neuron's reconstruction quality.
| Typically, named/annotated neurons have ``Traced`` status,
| the best quality.
| statusLabel (str or list of str):
| ``statusLabel`` is typically more fine-grained than ``status``,
| and mostly of interest during the construction of the connectome,
| not for end-users. The possible values of ``statusLabel`` do not
| correspond one-to-one to those of ``status``.
|
| rois (str or list of str):
| ROIs that merely intersect the neuron, without specifying whether
| they're intersected by input or output synapses.
| If not provided, will be auto-set from ``inputRois`` and ``outputRois``.
|
| inputRois (str or list of str):
| Only Neurons which have inputs in EVERY one of the given ROIs will be matched.
| ``regex`` does not apply to this parameter.
|
| outputRois (str or list of str):
| Only Neurons which have outputs in EVERY one of the given ROIs will be matched.
| ``regex`` does not apply to this parameter.
|
| min_roi_inputs (int):
| How many input (post) synapses a neuron must have in each ROI to satisfy the
| ``inputRois`` criteria. Can only be used if you provided ``inputRois``.
|
| min_roi_outputs (int):
| How many output (pre) synapses a neuron must have in each ROI to satisfy the
| ``outputRois`` criteria. Can only be used if you provided ``outputRois``.
|
| roi_req (Either ``'any'`` or ``'all'``):
| Whether a neuron must intersect all of the listed input/output ROIs, or any of the listed input/output ROIs.
| When using 'any', each neuron must still match at least one input AND at least one output ROI.
|
| group (int or list of int)
| In some datasets, the ``group`` ID is used to associate neurons morphological type,
| including left-right homologues. Neurons with the same group ID have matching morphology.
|
| serial (int or list of int)
| Similar to ``group``, but used for associating neurons across segmental neuropils in the nerve cord.
| Neurons with the same ``serial`` ID are analogous to one another, but in different leg segments.
|
| cropped (bool):
| If given, restrict results to neurons that are cropped or not.
|
| birthtime (str or list of str):
| cellBodyFiber (str or list of str):
| class\_ (str or list of str):
| Matches for the neuron ``class`` field.
| entryNerve (str or list of str):
| exitNerve (str or list of str):
| hemilineage (str or list of str):
| longTract (str or list of str):
| modality (str or list of str):
| origin (str or list of str):
| predictedNt (str or list of str):
| serialMotif (str or list of str):
| somaNeuromere (str or list of str):
| somaSide (str or list of str):
| Valid choices are 'RHS', 'LHS', 'Midline'
| subclass (str or list of str):
| synonyms (str or list of str):
| systematicType (str or list of str):
| target (str or list of str):
|
| label (Either ``'Neuron'`` or ``'Segment'``):
| Which node label to match with.
| (In neuprint, all ``Neuron`` nodes are also ``Segment`` nodes.)
| By default, ``'Neuron'`` is used, unless you provided a non-empty ``bodyId`` list.
| In that case, ``'Segment'`` is the default. (It's assumed you're really interested
| in the bodies you explicitly listed, whether or not they have the ``'Neuron'`` label.)
|
| min_pre (int):
| Exclude neurons that don't have at least this many t-bars (outputs) overall,
| regardless of how many t-bars exist in any particular ROI.
|
| min_post (int):
| Exclude neurons that don't have at least this many PSDs (inputs) overall,
| regardless of how many PSDs exist in any particular ROI.
|
| somaLocation:
| The ``somaLocation`` property of ``:Neuron`` objects contains
| the ``[X,Y,Z]`` coordinate (in voxels) of the cell body.
| ``NeuronCriteria`` does not allow you to match a specific coordinate,
| but you may set this argument to ``NotNull` (or ```IsNull``) to
| search for cells with (or without) a recorded cell body.
|
| tosomaLocation:
| Neurons which could not be successfully attached to their cell body do not have
| a recorded ``somaLocation``. Instead, they have an annotaiton on the cell body
| fiber, on the severed end extending out toward the cell body.
| Like ``somaLocation``, you can't match a specific coordinate using ``NeuronCriteria``,
| but you can use ``NotNull``/``IsNull``.
|
| rootLocation:
| Some (but not all) Neurons which have no soma in the tissue sample are tagged with
| a ``rootLocation``, indicating where they enter/exit the sample.
| Like ``somaLocation``, you can't match a specific coordinate using ``NeuronCriteria``,
| but you can use ``NotNull``/``IsNull``.
|
| soma (Either ``True``, ``False``, or ``None``)
| DEPRECATED. Use ``somaLocation=NotNull`` or ``somaLocation=IsNull``.
|
| client (:py:class:`neuprint.client.Client`):
| Used to validate ROI names.
| If not provided, the global default ``Client`` will be used.
|
| __repr__(self)
| Return repr(self).
|
| all_conditions(self, *vars, prefix=0, comments=True)
|
| basic_conditions(self, prefix=0, comments=True)
| Construct a WHERE clause based on the basic conditions
| in this criteria (i.e. everything except for the "directed ROI" conditions.)
|
| basic_exprs(self)
| Return the list of expressions that correspond
| to the members in this NeuronCriteria object.
| They're intended be combined (via 'AND') in
| the WHERE clause of a cypher query.
|
| directed_rois_condition(self, *vars, prefix=0, comments=True)
| Construct the ```WITH...WHERE``` statements that apply the "directed ROI"
| conditions specified by this criteria's ``inputRois`` and ``outputRois``
| members.
|
| These conditions are expensive to evaluate, so it's usually a good
| idea to position them LAST in your cypher query, once the result set
| has already been narrowed down by eariler filters.
|
| global_vars(self)
|
| global_with(self, *vars, prefix=0)
|
| rois_expr(self)

| Unlike all other fields, type and instance OR'd together.
| Either match satisfies the criteria.

Fetching neurons
Let’s say we want to find all antennnal lobe projection neurons (PNs). Their type nomenclature adheres to {glomerulus}_{lineage}PN (e.g. DA1_lPN)for uniglomerular PNs and a M_{lineage}PN{tract}{type} (e.g. M_vPNml50 = “multiglomerular ventral lineage PN mediolateral tract type 50) for multiglomerular PNs.
To get them all, we need to use regex patterns (see this cheatsheet):
[22]:
# Define the filter criteria
nc = neu.NeuronCriteria(type='.*?_.*?PN.*?', regex=True)
# Get general info for these neurons
pns, roi_info = neu.fetch_neurons(nc)
print(f'{pns.shape[0]} PNs found.')
pns.head()
369 PNs found.

The strongest connections are between PNs and Kenyon Cells (KCs). That’s not much of a surprise since there are thousands of KCs. For the sake of the argument let’s say we want to know where these connections occur:

Neuprint lets you query paths from a single source to a single target. For multi-source or -target queries, your best bet is to download the entire graph and run the queries locally using networkx or igraph.

So it looks like there are three separate 7-hop paths to go from M_vPNml53 to DN1a. Let’s visualize the neurons involved!
Fetching meshes & skeletons
You can fetch skeletons as SWCs directly via neuprint-python. For visualization however it’s easiest to load neuron morphologies via navis. For that navis wraps neuprint-python and adds some convenience functions (see also the tutorial):
[36]:
# Import the wrapped neuprint-python
# -> this exposes ALL base functions plus a couple navis-specific extras
# import navis
# import navis.interfaces.neuprint as neu
# client = neu.Client('https://neuprint.janelia.org', dataset='hemibrain:v1.2.1')
# Fetch neurons in the first path
bodyIDS = paths.loc[(paths.path == 0), 'bodyId']
# nl = neu.fetch_skeletons(paths.loc[(paths.path == 0), 'bodyId'])
# nl
xrefs = ['neuprint_JRC_Hemibrain_1point2point1:' + str(id) for id in bodyIDS]
nl_terms = vfb.terms(xrefs)
nl = [term.skeleton for term in nl_terms]
nl_terms.summary
Pulling 4 terms from VFB...
Warning: Substitution made. 'ALlv1 lineage neuron' was matched to 'adult ALlv1 lineage neuron'.

Plotting graphs
There are various ways of plotting static graphs. In theory Jupyter notebooks lend themselves to interactive graphs too but unfortunately DeepNote does not yet support the required libraries (e.g. ipywidgets). That being said: if you want to run this locally or on Google colab, check out ipycytoscape.
There are numerous options to do this but we will use networkx to plot a static graph:
[39]:
import networkx as nx
import numpy as np
# Initialize the graph
G = nx.DiGraph()
# Generate edges from the paths
edges = []
for p in paths.path.unique():
this_path = paths.loc[(paths.path == p)]
this_edges = list(zip(this_path.values[:-1], this_path.values[1:]))
for i in range(this_path.shape[0] - 1):
edges.append([this_path.bodyId.values[i], this_path.bodyId.values[i + 1], this_path.weight.values[i + 1]])
# Add the edges
G.add_weighted_edges_from(edges)
# Add some names to the nodes
nx.set_node_attributes(G, paths.set_index('bodyId')['type'].to_dict(), name='name')
[40]:
import matplotlib.pyplot as plt
# Draw using a simple force-directed layout
pos = nx.kamada_kawai_layout(G)
# We could draw everything in one step but this way we have more control over the plot
fig, ax = plt.subplots(figsize=(10, 10))
# Draw nodes
nx.draw_networkx_nodes(G, pos=pos, ax=ax)
# Draw edges
weights = np.array([e[2]['weight'] for e in G.edges(data=True)])
nx.draw_networkx_edges(G, pos=pos, width=(weights / 12).tolist())
# Add node labels
nx.draw_networkx_labels(G, pos=pos, labels=dict(G.nodes('name')), font_size=14)
# Turn axes of
ax.set_axis_off()
In general, I recommend exporting your graph to e.g. graphml and importing it into e.g. cytoscape if you want to explore an interactive network graph. see nx.write_gml
