Mining for specific genes

[Patrick Kearns]

Good evening (or morning, depending on where you live),

I'm interested in mining JGI's IMG for specific genes related to nitrogen cycling (nirS and nirK). I've been using the gene tool to select ~150 or so metagenomes at a time and then exporting the fasta files, this takes a good long while. Is there a better way to do this that would allow me to download the fasta sequence for all occurrences of my genes in all metagenomes?

Thanks
