Hi every body! I've encountered a problem with CDS of adenovirus's genes. I want to analyse the G/C ratio and codon usage of these genes. But there are "less-than-sign" in the CDS of some of these genes (e.g. CDS <11565..12297 http://www.ebi.ac.uk/ena/data/view/M73260&display=text ). One of the strange things is that the CDS length (12297-11565+1) isn't dividable by three. What is the meaning of "less-than-sign" in CDS?
Thanks for your replies!
