NAME

       phat - persistent homology utility from the PHAT library

SYNOPSIS

       phat [options] input_file output_file

DESCRIPTION

       phat is a simple persistent homology utility built using the PHAT library. It reads a (filtered) boundary
       matrix and applies an algorithm of the user's choosing to  compute  the  associated  persistent  homology
       module.

OPTIONS

       --ascii
              Use ASCII input file.

       --binary
              Use binary input file (default).

       --help Print help screen.

       --dualize
              Use dualization approach.

       --vector_vector,  --vector_heap, --vector_set, --vector_list, --full_pivot_column, --sparse_pivot_column,
       --heap_pivot_column, --bit_tree_pivot_column
              Choose a matrix representation. Default is --bit_tree_pivot_column.

       --standard, --twist, --chunk, --chunk_sequential, --spectral_sequence, --row
              Choose a reduction algorithm. Default is --twist.

ARGUMENTS

       input_file
              Input boundary matrix file.

       output_file
              Output file for persistence diagram.

                                                                                                         PHAT(1)
