Extract All Long Non-Coding Rna For Mouse

Hi all i was just trying to extract all the non-coding rna data for mouse from ucsc genome browser. from the table browser i got all the list of refseq genes. is it ok if i just grep those which contain NR as suffix for getting all long non coding rna? or is there any method for the same.

That will also contain microRNAs.

then how can i get only long non coding rna data? please give your suggestions

You might download kgXref and then grep "non-coding" kgXref | cut -f 2 | sort | uniq to get a list of names and then use that with grep (microRNAs aren't labeled as non-coding in kgXref). A more convenient way would be to just add the full name of each gene to the GTF file and then grep for "non-coding" in that (it's often convenient to have a gene_name field in GTF files). I expect there are instructions elsewhere on biostars on how to do that.

Edit: Of course, this all depends on the annotations containing "non-coding" in their names, which I can't guarantee is always the case.

Edit2: If you're willing to use the Ensembl annotation then life is easier (you can even just use biomart). I would normally recommend the Ensembl annotation anyway, it's much cleaner.

I found this (http://redmine.soe.ucsc.edu/forum/index.php?t=msg&goto=13211&S=eff182afb7e57f9d63444435c3804be2) on UCSC genome browser. This will also give you structural RNAs, transcribed pseudogenes along with non-coding RNA. You may set some length limit.
