The HeliSphere analysis pipelines are based on a software framework written in the Python programming language, called pypeline for Python pipeline. The pypeline framework provides efficient utilization of parallel compute resources for faster speed.

Before running any pipeline, you must download SRF files from the HeliScope and convert them to SMS files as described in Chapter 3, Analysis Workflows. In this section we will assume that pipelines are invoked in a directory called invocationDir. The SMS files are presumed to be in as sms subdirectory of invocationDir for all but the midrun pipeline; since that has only a single SMS file it is presumed to be in invocationDir itself.

All pipelines are invoked via the pypeline command. The first few sections describe asppects of this command that are common to all pipelines. The remainder describe the individual pipelines.
