  • What is the diff between kir3ds1_gen kir3ds1_nuc

    I am currently doing the kir alignment, but found there are two nucleotide sequence files on ftp://ftp.ebi.ac.uk/pub/databases/ipd/kir/ for a specific a locus:

    i.e. kir3ds1_gen and kir3ds1_nuc. which one should I use? can not find related explanation in the readme file.

    Also there is a overall file named KIR_nuc.fasta. but which seems not a sum up file joined by all locus?

    Any tips? Thanks!

    It appears that

    *_gen = genomic sequence
    *_nuc = exons/CDS

    Depending experiment your reads were derived from/questions you want to ask choose accordingly.

      Thanks GenoMax again. You helped me on the other question. I might want to find out the all kir genes in a batch of sequence data.

      When I go the the ftp site, I found kir_nuc.fasta and many other individual locus sequences (i.e. kir3ds1_nuc.fasta), the kir_nuc.fasta name seems to be an all-in-one sequence file. But when I concatenate all the other locus sequence, which the sequence content is different from kir_nuc.fasta. So if I want to find all kir genes, should I use the kir_nuc.fasta or create a new one which concatenate all single locus sequence together?

      Many thanks!

        I am going to suggest that you contact IPD support to see if you can get an authoritative answer: http://www.ebi.ac.uk/support/ipd.php

        You could blast the kir_nuc.fasta against the concatenated file to see if everything is represented in the large single file. My hunch is that it is likely true.

            Strategies for Sequencing Challenging Samples
            by seqadmin


            Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
