Is it necessary to write shell script wrappers for executable programs in order to describe these executables as Pipeline modules?
The pipeline environment does not require any modifications, rebuilds, redeployments of existent tools which provide a well-defined command-line executable invocation syntax. However, sometimes it may be helpful or necessary to wrap executable tools via external shell scripts (e.g., tcsh, csh, bash, etc.) Examples of these situations include: * instances of command-line executable tools that have a well-defined invocation syntax, however, output implicit number, types and formats of results/data that can not be inferred a priori e.g. VolumeMultipleRegression tool.
