An open structure and toolkit for organizing large-scale, sample-intensive biological research projects.
PEP, or Portable Encapsulated Projects, is a community effort to make sample metadata reusable. PEPs decouple metadata from analysis by providing:
A PEP is written using a familiar yaml + csv format that can be read by our R and Python packages, as well as by workflow frameworks. PEP is your metadata solution for sample-intensive research projects.
- a standardized metadata structure;
- a metadata validation framework; and
- programatic metadata modifiers.
Start by writing your metadata in PEP format, and immediately benefit from metadata organization tools written in R and Python.
Handle input sample metadata formatting, parsing, and validation with our R or Python APIs, making your tool able to process PEP-compliant projects.
