        We can't use that currently, because a few output-datatypes, like the fastsearch index do not support merging. We need to patch galaxy to not abort in such a case

**What this tool does**

The compound converter combines several Open Babel command prompt converters into a single easy-to-use tool. It interconverts various chemistry and molecular modeling data files. The output format can be specified as well as several parameters. Some parameters are available for all tools (e.g. protonation state and pH) while others are specific for a given output format (e.g. exclude isotopes for conversion to canSMI).
