1. A method for determining an identity of a nucleotide at a position, comprising:
- a) providing a device which measures color in more than one detector channel, nucleic acid, polymerase, and a mixture of labeled and non-labeled reversible terminators, said labeled reversible terminators comprising a label linked to a nucleotide analogue, said label producing color, said color detected in two channels;
b) incorporating, with said polymerase, a first nucleotide analogue from said mixture into said nucleic acid at a position;
c) detecting the label of said incorporated first nucleotide analogue in two channels with said device; and
d) determining the identity of the incorporated nucleotide at said position.

Abstract
The invention provides methods and compositions, including, without limitation, algorithms, computer readable media, computer programs, apparatus, and systems for determining the identity of nucleic acids in nucleotide sequences using, for example, data obtained from sequencing by synthesis methods. The methods of the invention include correcting one or more phenomena that are encountered during nucleotide sequencing, such as using sequencing by synthesis methods. These phenomena include, without limitation, sequence lead, sequence lag, spectral crosstalk, and noise resulting from variations in illumination and/or filter responses.
