Chapter 6 Workflow and Steps
Researchers want to control the data processing steps involved in the analysis of large complex data. A record of what analysis is performed is key for reproducible science. Hence Tercen has a graphical workflow editor. This allows researchers to use pre-defined workflows (e.g. taken from the app library) or if the researcher wishes, can create workflows from scratch.
A workflow consists of a series of steps. Each step is explained below.
Table step
Allows a researcher to select a dataset. The dataset requires to be uploaded to Tercen before it is visible for selection in the Table step.
Data step
Allows a researcher to create a projection for visualization and computation. For a list of computations see the operator catalog.
Gather step
Allows a researcher to gather many factors into one factor.
Join left step
Allows a researcher to link to external data.
Join right step
Allows a researcher to link to external data.
Query Data step
Allows a researcher to perform a project without a computation.
External View Data step
Allows a researcher to connect to an external web apps (i.e. shiny app).
Wizard step
Maps the factors in your workflow with what is in the data.
Input step
Used as the first step in an app workflow.
Output step
Used as the last step in an app workflow.
App step
Is a generic term for a customized step. They are usually taken from the app library.
Export step
Used to export the result of a data step as a table
