Studies are collections of material and resources used within the investigation. -You need to place each study in a unique subdirectory. Material or experimental samples, as well as external data files, can be stored as virtual sample files (containing unique identifiers) in the resources directory. To describe the sample or material creation process, you can store protocols in the designated sub-folder.
-For each study, an isa.study.xlsx file following the ISA study model needs to be present to specify the characteristics of all material and resources, such as a certain strain. Resources might include external data (e.g., knowledge files or result files) that need to be included and cannot be referenced due to external limitations. Resources described in a study file can be the input for one or multiple assays.
+Workflows in ARCs represent processing steps used in computational analyses and other data transformations of assays to generate run results. Typical examples include data cleaning and preprocessing, computational analysis, or visualization.
+All files belonging to a specific workflow need to be stored in a single sub-directory. +This also includes a mandatory per-workflow executable CWL description (v1.2 or higher), which can contain a tool or workflow description.
+We highly recommend to include a reproducible execution environment description in form of a Docker container description for tool descriptions.
