Input Network

PASTE YOUR NETWORK HERE...
...AND YOUR POTENTIAL NETWORK HERE
(if you have one)...





***

...OR UPLOAD A TEXT FILE
FOR YOUR NETWORK...





***

...AND ONE FOR YOUR POTENTIAL
NETWORK (if available)...





...OR GENERATE AND ANALYZE A NETWORK WITH PREDEFINED STRUCTURE:
NO YES


NUMBER OF NODES (<99)  

DEGREE OF RANDOMNESS (0-9)  


STRUCTURE:

OVERLAP

SEGREGATION

MODULARITY (Number of modules   )





Analysis Setup

1) SPECIFY THE KIND OF YOUR NETWORK:

UNDIRECTED
DIRECTED UNIMODE
DIRECTED BIPARTITE




***

2) COMPUTE POTENTIAL NETWORK BASED ON ESTIMATION OF TROPHIC LEVEL?


(if 'yes', the network will be treated as 'DIRECTED UNIMODE')
NOYES


Trophic measure (Path to Basal Resource)


Shortest Path
Chain Averaged Path
Longest Path



Consuming Rule (Sp1 consumes Sp2 if:)


  (Threshold Rule)     TL(Sp1)  >  TL(Sp2)

  (Step Rule)     TL(Sp2)+   ≤  TL(Sp1)  <  TL(Sp2)+


TL(Sp) = Trophic Level of Sp



***

3) EXCLUDE CANNIBALISTIC INTERACTIONS (I.E. SELF LINKS) FROM COMPUTATION?


NO YES



***

4) SELECT THE FRACTION OF PAIRWISE COMPARISONS TO BE PERFORMED (0-1)*:




*the recommended value is 1; use lower values only for exploratory analyses, or in case your network is exceedingly large.
