Hierarchical task tree retrieved from the empirical study and the literature research. It represents the typical pipeline of a bioinformatics research using different abstraction levels. Particularly, it is composed of four main-phases: Objective Definition, Data Extraction, Data Analysis and Result Analysis. Each of these is composed of many children that allows to better specify and clarify the steps that are usually computed
