A workflow is an arrangement of modules in a specific way customized for a specific job. For example, you can build a workflow for scratch assay analysis by starting with an image import module, then a module to convert the image to OME-TIFF format followed by a module for image filtering, then a module for thresholding and finally a module for plotting. Any user can easily create a workflow by either editing an existing public workflow or by putting together a new workflow from scratch. You do not need to download any software on your system to build or run modules. All the necessary tools are available online, use any browser on any device to work with modules.
