Third Party (TPA) sequence records were initially intended to capture experimentally (TPA:experimental) or inferentially (TPA:inferential) confirmed annotations that were not previously submitted to INSDC with the initial primary sequence record.
All TPA records require a peer-review publication for describing the analysis done to generate the annotations .

Please note that due to the complexity of the submission process and changes to the technology used to analyze data, INSDC will no longer accept new submissions of type TPA: experimental and TPA: inferential after January 2025.
We will continue to accept new TPA-assembly sequences.
