@mikhail.shugay I think this is a great idea, and would certainly be of use to the community. I have had similar ideas, but for a BCR database, and have made a start collating these from the literature in a fairly crude manner. I have been thinking about the best ways to share this database, and also to encourage people to submit their own sequences (trawling the literature, and manually typing in sequences is not ideal), but have not started developing anything yet. Do you think it would be possible to make a version of your database where BCR’s could be submitted? I have found my database to be very useful for initial annotation of our RepSeq datasets collected following vaccination, and increases the amount of interesting data we can extract from them.
