Retrieving Fasta Sequences From Multiple Databases

Question

[Prakki Rama]

Hi all,

I have list of identifiers from different databases (say geneid from genbank, gene name, ensembl ID, zfin id, unigene id etc). Could i please know if there is any simple way to extract fasta sequences for all these identifiers at one go?

Thanks in advance.

I think that all contemporary data-banks provide an API (an Application Programming Interface) implemented in a variety of languages or directly queryable over HTTP using REST etc. It will be the simplest solution to use them without downloading databases locally. NCBI folks explain that here.

Thank you very much, but in my case, i have changed all the id's from different databses to a single database id's using biogps and biodbnet softwares and worked on it.
