We have published IGHV germline sets for laboratory mouse strains BALB/c and C75BL/6, as recently reported in preprint by Jackson et al.The sets will be curated by the AIRR Community Germline Database Working Group with the aim of maintaining sets that are tuned for use in AIRR-seq, taking advantage of the latest research. We hope… Continue reading First Germline Sets Published on OGRDB
IGH Analysis updated
The analysis of the Human IGH dataset has now been updated to determine novel sequences based on the actual V length inferred by igblast, enabling greater recognition of variation at the 3′ end. To provide greater detail on the analysis, we now provide the commit id of the pipeline version used for analysis in the… Continue reading IGH Analysis updated
Introduction to OGRDB
Introduction to OGRDB In recent years it has become possible to sequence immune receptor repertoires (immunoglobulins and T cell receptors) at great depth. The accurate analysis of these repertoires requires a comprehensive understanding of the germline genes that give rise to the repertoire through V(D)J gene recombination. Even for well-studied species such as humans and… Continue reading Introduction to OGRDB
New inferred sequences accepted by IMGT
A new batch of inferred receptor sequences, submitted for review through OGRDB, has been accepted by IMGT and should be added to their reference sets shortly. This batch included the first IGK and IGL alleles. We have now affirmed a total of 32 sequences, details of which can be found on the Sequences page.
Submitting inferences to OGRDB
If you have identified previously undocumented alleles in AIRR-Seq repertoires, we invite you to submit them to OGRDB for review and possible inclusion in published germline reference sets. At present, you can submit human IG or TR V-sequences for consideration. We hope to extend this to cover more species and loci soon. Qualification criteria To… Continue reading Submitting inferences to OGRDB
Creating a select set
A select set is a set of reads taken from a single repertoire that directly support a specific inference. In outline, the process to create the set is as follows: For a paired-end-read dataset, merge all paired-end reads Align reads to the inferred allele reference Filter the output to an identity of at least 96%… Continue reading Creating a select set
OGRDB – Depositing records in NIH repositories
At the end of this deposition process, NCBI will contain two types of record for use in your submission: A sequence record for each inferred sequence you intend to submit. One or more select sets for each inferred sequence. The deposition process for each type is detailed below. As sequence records refer to select sets,… Continue reading OGRDB – Depositing records in NIH repositories
OGRDB – Depositing records in ENA repositories
At the end of this deposition process, ENA will contain two types of record for use in your submission: A sequence record for each inferred sequence you intend to submit. One or more select sets for each inferred sequence. The deposition process for each type is detailed below. As sequence records refer to select sets,… Continue reading OGRDB – Depositing records in ENA repositories
Creating an OGRDB Submission
Pre-Requisites Before submitting inferred sequences with OGRDB, you should have run OGRDBstats on each repertoire: otherwise, please follow steps in the overall submission process before continuing. Having run OGRDBstats, you should have output files (pdf and csv) for each repertoire from which inferences have been derived. The project should be deposited in a long-term repository,… Continue reading Creating an OGRDB Submission
IARC Submission Guide Updated
We welcome submissions of previously undocumented alleles of human receptor genes. The Submission Guide explains the process, which involves deposition of sequences and sequence sets in NIH or ENA repositories. Your submission will be reviewed by AIRR‘s Inferred Allele Review Committee, and, if there is sufficient evidence, the sequence will be published on this site… Continue reading IARC Submission Guide Updated
