The open source ISA metadata tracking tools help to manage an increasingly diverse set of life science, environmental and biomedical experiments that employing one or a combination of technologies.

Built around the ‘Investigation’ (the project context), Study’ (a unit of research) and ‘Assay’ (analytical measurement) general-purpose Tabular format, the ISA tools helps you to provide rich description of the experimental metadata (i.e. sample characteristics, technology and measurement types, sample-to-data relationships) so that the resulting data and discoveries are reproducible and reusable.

The ISA API aims to provide you, the developer, with a set of tools to help you easily and quickly build your own ISA objects, validate, and convert between serializations of ISA-formatted datasets and other formats/schemas (e.g. SRA schemas). The ISA API is published on PyPI as the isatools package.

isatools is currently only supported in Python 3.4+.
