Abstract
The present invention relates to methods for resolving convoluted peaks in a chromatogram into one or more constituent peaks using peak resolution values. The peaks methods of the invention determine empirical peak resolution values of “well-defined” or “isolated” peaks in the data, then extrapolate these empirical resolution values to peaks in neighboring regions to predict the number of constituent peaks at a given peak position. Predicted peak resolution values are compared to observed peak resolution values of low-resolution or convoluted peaks to determine the number of constituent peaks in the convoluted peaks. These methods enable extension of the region of data that can used for identifying nucleotide sequences, and increase base-calling accuracy in the low-resolution region (end region) of data.
