Search for sequence homology against various species

Question

[lorenzinip]

Hi all,

I have thousands of DNA sequences in a fasta file and I would like to query each of them for similarity/homology against several species (e.g human, mouse, rat, fly...).

Output should return a similarity score for each sequence preferably

Any idea about how to proceed with a most efficient way?

Thanks
