DDBJ is Japan's official nucleotide sequence database and a founding member of the International Nucleotide Sequence Database Collaboration (INSDC).

Operated by the National Institute of Genetics (NIG) in Mishima, DDBJ serves as a critical global hub for genomic data exchange. It synchronizes records daily with GenBank (USA) and the European Nucleotide Archive (ENA) to ensure a redundant, universal record of life's blueprints. The platform hosts specialized services like the DDBJ Sequence Read Archive (DRA) for raw output and the Japanese Genotype-phenotype Archive (JGA) for secure clinical data. By managing over 2.5 trillion bases of sequence information, DDBJ provides the raw material for modern bioinformatics and drug discovery.

## Recent Public Talks and Demos

### [Contrasting Language Omics Pretraining](https://lausanne.aitinkerers.org/talks/rsvp_ZjMIQM_LY9M)

CLOP is an adaptation of OpenAI's CLIP but for Omics - in this demo, genomics. The model is trained on fasta, bed and gff files (representing genomes of different species and their annotations) to learn meaningful representations for further retrieval, classification and generation purposes. The model embeds DNA sequences according to species and biotype (e.g. exon, long non coding RNA, pseudogene, etc.)
