Abstract: Methods and systems for detecting and characterizing a pattern (or patterns) of interest in a low signal-to-noise ratio (SNR) data set are disclosed. One method is a two-stage Likelihood pipeline analysis that takes advantage of the benefits of a full Likelihood analysis while providing computational tractability. The two-stage pipeline may include a first stage including the application of approximate Likelihood functions in which one or more of the following assumptions or modifications may be applied: (i) the pattern of interest and background are at a specified position in a segment of the data set under examination; (ii) the SNR is low; and (iii) measurement noise can be represented in such a form that all non-position parameters of the representation are linear with respect to the derivative of the Log Likelihood versus lambda. The second stage may include a full Likelihood analysis.

Abstract: Methods and systems for detecting and characterizing a pattern (or patterns) of interest in a low signal-to-noise ratio (SNR) data set are disclosed. One method is a form of a two-stage Likelihood pipeline analysis for differentiating multiple closely-spaced spots that takes advantage of the benefits of a full Likelihood analysis while providing computational tractability. The two-stage pipeline may include a first stage including the application of approximate Likelihood functions. The second stage may include a full Likelihood analysis. Once a pattern of interest instance is characterized, it may be subtracted from the underlying data, and the two-stage analysis may be performed on the reduced data to detect a further pattern of interest proximate the characterized pattern.

Abstract: Methods and systems for detecting and characterizing a pattern (or patterns) of interest in a low signal-to-noise ratio (SNR) data set are disclosed. One method is a two-stage Likelihood pipeline analysis for detecting patterns of interest captured with multiple data capture regimes that takes advantage of the benefits of a full Likelihood analysis while providing computational tractability. The two-stage pipeline may include a first stage including the application of approximate Likelihood functions. At the first stage, the effects of penetrance of each pattern of interest into each data capture regime may be accounted for. The second stage may include a full Likelihood analysis.

Abstract: Methods and systems for detecting and characterizing a pattern (or patterns) of interest in a low signal-to-noise ratio (SNR) data set are disclosed. One method is a two-stage Likelihood pipeline analysis that takes advantage of the benefits of a full Likelihood analysis while providing computational tractability. The two-stage Likelihood pipeline may include, at either stage, the calculation and use of one or more of a false positive rate, a standard error, and a multi-factor landscape involving a gradient and/or Hessian of a Likelihood ratio.
