Graph of C. elegans Neuron Classes

The source of our modified database includes the following data:

Connections between cells or cell classes are listed in 3 files:
Albertson_Fig, derived from (2);
White_Fig, derived from (4);
White_Table, derived from (4);

Structure of the database:

name_neurons.txt: Similar to the original name_neurons.txt of (1), this file list the name of the neurons and the class of the neurons in a textfile. Our version contains the following corrections:
- some classes are missing from the original one, but appear in the files named above (e.g. G)
- some cells appear with a name in the files named above different from the original one (e.g. CEPshDL=CEPDL)
- some classes appear with a name in the files named above different from the original one (e.g. m1=M1)
- we put a # at the end of the corrected lines
ellista.txt: This is the edge-list of the braingraph of C. elegans. Two classes are in the same row if there are any connections between them (without considering the direction or the type of the connection)
- we left out the "-" or the "MUSCLE" classes out from the original database
- the number next to the pair of cells refers to the number of the found connections in the database
foxamok.txt: this text file contains the degree of the classes (i.e., the number of edges, connected to them), ordered by name; foxamok_ordered.txt: contains the degree of the classes in decreasing order.
matrixgyarto.py: the script which created "ellista.txt" from the original database (Ce_synapse)
foxamlalo.py: the script which created "foxamok.txt" and "foxamok_ordered.txt" from "ellista.txt"
