Length interval of long non-coding RNAs?

[tigerxu]

According to some references, long non-coding RNAs (lncRNAs) is composed of non-coding RNAs (ncRNAs) with long transcript length (>200 nt).

I'm wondering how I can know the length distribution of all publicly available lncRNAs? Are many lncRNAs greater than 1,000 nt? How long is the maximum lncRNAs at present?

Thanks!

If you are speaking about human lncRNAs, you can get a file from gencode containing all lncRNAs in single line fasta format (http://www.gencodegenes.org/releases/19.html):

On this file you can do the following to get the length of all lncRNAs:
grep -v "^>" ./gencode.v19.lncRNA_transcripts.fa | awk '{print length($0)}'

Many thanks for your advice! I got it.
