The basic processing view comprises a single main panel, showing all the available parameters. Certain
modules can be set by the workflow creator to be optionally enabled (

) or disabled (

), while required modules have this icon greyed out
(

). Any parameters which are incorrect (e.g. paths to
files that don't exist) are highlighted in red with an accompanying error icon (

). Modules can also be grouped into sections, which can be
independently expanded (

) or collapsed (

) by clicking anywhere on the associated header.
