An index of substitution saturation and its application.
We introduce a new index to measure substitution saturation in a set of aligned nucleotide sequences. The index is based on the notion of entropy in information theory. We derive the critical valuesExpand

An evaluation of new criteria for CpG islands in the human genome as gene markers
MOTIVATION Recently, more stringent criteria for CpG islands have been introduced to exclude Alu repeats, thereby enabling a higher proportion of C pG islands associating with genes to be identified. Expand
