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. 

Choose Function:  
Filtration:
If computing persistent Homology
choose a filtration: Zero: All faces have filtration 0 Dimension: A ndimensional 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.
