Abstract: Systems and methods determine based methylations in analyzing nucleic acid molecules. Embodiments may use kinetic signals produced by a DNA polymerase during single-molecule sequencing. The use of kinetic signals of adaptor sequences may allow for determining the methylation patterns proximal to the ends of a DNA fragment. Deep learning models that can capture local and global signal patterns can be trained to detect the base methylations using these features, with improved performance. Deep learning models may include a convolutional neural network that preferentially captures the features of local signal patterns, with the integration of a transformer model that preferentially captures the features of global signal patterns. The improved performance in the determination of base methylation may lead to more accurate diagnoses of subjects. Accurate measurement of DNA methylation may have several other clinical applications.
