UCNEbase 2013, Ultra-Conserved Sequence Elements.


Vertebrate ultraconserved sequence elements (UCNEs) from UCNEbase. The collection is offered: (i) as an oriented "regions" SGA file where positions on the + and - strand indicate the beginning and end of a UCNE, respectively, and (ii) as an unoriented SGA file where the positions indicate the center of a UNCE.



From H. sapiens (Feb 2009 GRCh37/hg19).


Filename Description Feature GEO-ID
1 ucne_hg19.sga UCNEs from UCNEbase UCNE -

Technical Notes

The input BED file was converted into SGA and FPS format using custom Perl scripts available from the MGA ftp sitei (https://epd.expasy.org/ftp/mga/). Chromosome name conversion and generation of the FPS files was done with chr_replace_sga.pl and sga2fps from ChIP-Seq v. 1.5.3.
