Artificial intelligence driven enhancement of motion blurred sequencing images enables enhanced sequencing that determines a sequence of bases in genetic material with any one or more of: improved performance, improved accuracy, and/or reduced cost. A training set of images taken after unreduced and reduced movement settling times during sequencing is used to train a neural network to enable the neural network to recover enhanced images, as if taken after the unreduced movement settling time, from unenhanced images taken after the reduced movement settling time.

AI-driven enhancement of motion blurred sequencing images

A method for extending a depth of field of a nucleic acid sequencer may comprise optimization steps which are repeated one or more times, in which a result of passing light through an objective lens and a mask is compared with an ideal result, and any discrepancy is used to update the mask. Such a mask may be incorporated into a nucleic acid sequencer which adds fluorescent tags to nucleic acid sites and then detect light emitted from the fluorescent tags, thereby extending the sequencer's depth of field.

Methods of determining an ideal gain for a detector in a light detection system of a flow cytometer are provided. Methods of interest include irradiating a flow stream with light from a light source, incrementally increasing the gain of the detector such that the detector collects light from the flow stream at each of a plurality of successively increasing gains, obtaining a baseline noise level from the detector at each gain in the plurality of successively increasing gains, calculating a limit of detection (LoD) for each gain in the plurality of successively increasing gains, and assessing the calculated LoDs to determine the ideal gain. Systems and computer readable storage media for practicing the invention are also provided.
