Airr

Fixed a bug in the python reference library causing start coordinate values to be empty in some cases when writing data.

Schema Release Notes

Definition change for the coordinate fields of the Rearrangement and Alignment schema. Coordinates are now defined as 1-based closed intervals, instead of 0-based half-open intervals (as previously defined in v1.1 of the schema).

Reference Library Release Notes

Several changes to the python and R reference library to support the new schema coordinate definition and improve validation. See the package release notes for details:

Initial official release of the AIRR Data Representation standards and associated python and R reference libraries.

An early revision of the AIRR definitions with corresponding reference library.

This is the V1 release of the Standard for the Minimum information about an Adaptive Immune Receptor Repertoire Sequencing Experiment (MiAIRR V1).

Description of MiAIRR V1 can be found in this article:

The V1 release defines the primary data elements as the minimum information to be archived with an adaptive immune receptor repertoire sequencing experiment. The computational specifications, data file formats, and reference libraries are still being finalized and will be released in a later version.
