Where Can I Download Lincrna Feature Files For The Mm9 Genome Build

Does anyone know where I can get a valid mm9 gtf or gff3 lincRNA dataset? I need relationship data within these files.

So far my searching has lead me to believe that only coordinate files exist. The only feature type I have found is 'exon'

Thank you very much!

subtract the lincRNA from the Ensembl annotation:

wget ftp://ftp.ensembl.org/pub/release-68/gtf/mus_musculus/Mus_musculus.GRCm38.68.gtf.gz
zgrep lincRNA Mus_musculus.GRCm38.68.gtf.gz > lincRNA.gtf

*the last mouse assembly is mm10, I'm almost sure that Ensembl is using that annotation, if you need mm9 maybe you will need to search in previous releases.

Yes this annotation is much better! However, there are way fewer lincRNAs than I have seen in other sets.

yes, but consider that lincRNA biology is still in research. Recently I take a look of the lincRNAs printed in a human microarray, many probes were bad, some marks introns and others are alternative transcripts from a large coding gene. Be careful with annotations.

The quality of the annotations has been bothering me since I have started looking into lincRNAs.
