# Interfacing with an external computational homology program called CHomP

I have an external program called CHomP.

I am trying to send a command to CHomP via RunThrough, and read the output string.

It is meant to give the Betti numbers of a simplicial complex defined as $d$-tuples in a text file.

I have

RunThrough["/Users/alex/CHomP/build/bin/chomp-simplicial", "/Users/alex/CHomP/examples/new6.cub"]


which is meant to run

/Users/alex/CHomP/build/bin/chomp-simplicial /Users/alex/CHomP/examples/new6.cub

in the terminal. But I get a syntax error. What is wrong here? The output to the terminal is

Betti Numbers: 1 1 0 0

If you need it, the text file new6.cub is a list of simplices defined as tuples of vertex names...

One can use OpenRead with ! at the beginning to indicate the string is a command for the terminal.
