Figure 4. — A workflow for protein function analysis. The workflow is represented as Directed Acyclic Graph (DAG) in WebLab. The rectangular node of the DAG means a single tool or a defined Macro; the diamond node stands for operators which control the execution of workflows. WebLab supports two types of operators: condition operator (for example, nodes 1 and 3 in figure) determines following analysis depending on a given condition (for example, the workflow in figure will try to translate the input sequences by transeq for DNA sequences); parallel operator (for example, node 4 in figure) is used to share incoming data among several parallel analysis tools or combine several incoming data into one sink.
