•sparse (sparse distance matrix in sparse triplet format)

•binary (lower triangular distance matrix in binary format)

--dim <k>

Compute persistent homology up to dimension k

--threshold <t>

Compute Rips complexes up to diameter t

--ratio <r>

Only show persistence pairs with death/birth ratio > r
