Architecture and features

A workflow is a series of processing steps connected together so that the output of one step is used as the input of another. Processing steps implement data analysis tasks such as data importing, statistical tests and report generation. In Anduril, processing steps are implemented using components, which are reusable executable code that can be written in any programming language. Components are wired together into a workflow, or a component network, that is executed by the Anduril workflow engine. Workflow configuration is done using a simple yet powerful scripting language, AndurilScript. Workflow configuration and execution can be done from

Anduril 1.0: AndurilScript language

Hello world in AndurilScript is simply std.echo("Hello world!") Commenting follows the syntax of Java: // A simple comment /* Another simple comment */ /** A description that will be included in component description */ Components are called by assigning their calls to named component instances. Names cannot be re-used within a single workflow. There are special components for input files that include external files to the script. Supported atomic types are integer, float, boolean and string, and typing is done implicitly. in1 = INPUT(path="myFile.csv") constant1 = 1 componentInstance1 = MyComponent(inputPort1 = in1, inputParam1 = constant1) Workflows are constructed by assigning outputs of component instances to inputs of following components. componentInstance2 = AnotherComponent(inputPort1 = componentInstance1.outputPort1) Component instances can also be wrapped as functions. function MyFunction(InType1 in1, ..., optional InTypeM inM, ParType1 param1, ..., ParTypeP paramP=defaultP) -> (OutType1 out1, ..., OutTypeN outN) In addition to standard if-else and switch-case statements, AndurilScript also includes for-loops. // Iterates over 1, 2, ..., 10 array = record() for i: std.range(1, 10)

Extensibility

Anduril can be extended on multiple levels. Users can add new components to existing component bundles. However, if the new component or components carry out tasks that are not related to existing bundles, users can also create new bundles.

The framework provides a relational database that represents a graph of biological entities such as genes, protein, drugs, pathways, diseases, biological processes, cellular components, and molecular functions. In addition, there is a wide set of analysis and accession tools built on top of this data. The great majority of these tools are implemented as Anduril components and functions.
