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.

Thanks mate!
