roundtrip(1)

roundtrip1

A comparison program for testing roundtrip conversion

Usage

roundtrip filename filename

Overview

The roundtrip program is essentially a “chemical diff.” That is, it will return with an error if two files do not have the same number of atoms, the same number of molecules, and where appropriate, the same element and coordinates for each atom.

Options

If given two filenames, roundtrip will guess the file format from the extension.

Examples

Compare two files created via a roundtrip test

roundtrip 3d.sdf 3d.xyz
