Minimum information required for reporting samples associated with the Tree of Life Programme (https://www.sanger.ac.uk/programme/tree-of-life/).
A Study is a container for a sequencing investigation that may comprise multiple experiments. The Study has an overall goal, but is otherwise minimally defined in the SRA. A Study is composed of a descriptor, zero or more experiments, and zero or more analyses. The submitter may decorate the Study with web links and properties.
