Input Graph: Input a directed graph as:
First line is always the string "dim 0".
Second line is a list of integers,
where the i'th integer is the filtration value of vertex i.
Third Line is always the string "dim 1".
Each subsequent line is an edge i->j
written as "i j" or "i j f",
where f is the filtration value.
Select a File to Load: Select a text file containing a graph
and then load it into box above.
Or load an example graph.
Filtration: If computing persistent Homology
choose a filtration:
Zero: All faces have filtration 0
Dimension: A n-dimensional face has filtration n
Max: Max of boundary filtration values
Sum: Sum of boundary filtration values
Max and Sum require an edge filtration to be inputted.
Approximate: Set an approximate value to skip certain computations when taking to long, see documentation for further details.
Min Dim: Selecting the smallest dimension to consider.
Max Dim: Selecting the largest dimension to consider.
