Given the species below whose genomes are fully sequenced and annotated in NCBI. I only need to obtain all the rna genes for further processing. someone out there with a script that can do the task perfectly. my last quiz went poorly because i never gave examples. well here are more than examples. Alternatively i may use 16S rna for the start. share that script someone...urgent help needed

You got some nice answer for your previous question. Can you please validate one ?

what do you mean by 'rna genes'?

Use the NCBI utilities: ESearch and EFetch (many examples here, on biostar) with the following sample query:

"Bacillus  subtilis  168"[ORGN] biomol_mRNA[PROP]

unfortunately, many organisms are poorly annotated and you won't easily find the mRNA sequences. May be you could just filter the sequences using a size criteria with the [SLEN] operator ?

I can't give you a script, but I can offer the IMG resource as a way to quickly get RNA sequences. If you go to an organism detail page they offer a link that looks like this to get the RNA sequences.

Here's an example of one of the B. cereus strains:

In the "Genes Total Number" section of the table there is a link to various breakdowns of the RNA sequences. You can click the hyperlinked number to get the list, and then do various operations on the results sets.

Keep in mind that is just one of the many strains that are listed there. I did a "find genomes" search for cereus, and sorted by "finished" to explore them.

Alternatively you could select the species and set that at IMG as your query subset, then do a gene search for the specific ones you want, export those all at once.

(Sorry to be late to this, I was away for Thanksgiving...)
