Comments on Network Viewer:

Network viewer is a force-graph of the C. elegans neural network. Nodes represent neurons and edges represent chemical (gray arrows) or electrical (blue dotted line) synaptic connections. Edge thickness correspond to the number of electron microgpraphs in which the connectivity was scored. Nodes can be clicked and dragged to different locations. Mouseover a node and the node and all its adjacent edges will be highlighted in red. Mouseover an edge and the edge weight will be shown in the upper left corner. To view the entire network just click 'Draw Network'. However, read below for ways to filter the data. NetworkViewer is supported on most major web browsers except IE.

Database

The Database dropdown allows the user to choose which dataset should be graphed.

Keep file

Here you can upload a text file that lists all the neurons in the dataset that should be graphed. It should have the following format:

neuron1
neuron2
neuron3
...
neuronN

An example file of the hub and spoke circuit for the Hermaphrodite Anterior dataset can be found here.

Remove file

Here you can upload a text file that lists all the neurons in the dataset that should not be graphed. The remove file should have the same format as the 'Keep File'.

Group file

Here you can upload a text file that lists how neurons should be grouped. It should have the following format:

neuron1,neuron2,neuron3,-->,group1
neuron4,neuron5,neuron6,neuron7,neuron8,-->,group2
neuron9,neuron10,-->,group3

Note that it is required that the neurons in the group and the group name be separated by '-->'.

Minimum Edge Weight

This sets minimum threshold for edge weights. This can currently be set as high as 15. If for some reason you need it set higher, then email me.

Chemical/Electrical check boxes

Uncheck these boxes if you do not want to graph chemical or electrical edges.
