Hi Thomas,

 CDS means coding sequence.

look at 

In a GenBank DNA sequence entry, "cds" stands for coding sequence. A coding sequence is a subsequence of a DNA sequence that is surmised to encode a gene. A coding sequence begins with an "ATG" and ends with a stop codon. In the cases of spliced genes, all exons and introns should be within the same cds. In the systematic sequencing project, coding sequences are called "ORF"s. The difference between the two names (cds or ORF) allows one to tell from which kind of larger sequence the subsequence (cds or ORF) is derived.
