Patent Images
1. A system of detecting molecules, said system comprising:
- (a) a solid support comprising molecules associated with a site on the solid support, wherein the site comprises at least two different types of molecules comprising nucleic acids;
(b) a detector configured to detect at least one signal corresponding to aggregates of molecules comprising nucleic acids at the site;
(c) a first data processing module configured to provide an initial estimate of the amount of signal corresponding to each of the at least two different types of molecules comprising nucleic acids at the site;
(d) a second data processing module configured to calculate the amount of signal corresponding to each of the at least two different types of molecules comprising nucleic acids at the site using the initial estimate, thereby obtaining a signal estimate; and
(e) a third data processing module configured to iteratively update the initial estimate until the signal estimates converge, thereby detecting molecules associated with the site.

21. A system of detecting molecules, said system comprising:
-
(a) a solid support comprising molecules associated with a site on the solid support, wherein the site comprises at least two different types of molecules, wherein the at least two different types of molecules comprise nucleic acids; (b) a detector configured to detect at least one signal corresponding to aggregates of molecules comprising nucleic acids at the site; (c) a first data processing module configured to provide an initial estimate of the fraction of signal corresponding to each of the at least two different types of molecules comprising nucleic acids at the site; (d) a second data processing module configured to calculate the fraction of signal corresponding to each of the at least two different types of molecules comprising nucleic acids at the site using the initial estimate, thereby obtaining a fraction estimate; and (e) a third data processing module configured to iteratively update the initial estimate until the fraction estimates converge, thereby detecting molecules associated with the site.

22. A system for detecting molecules, comprising:
-
(a) a solid support comprising molecules associated with a site on the solid support such that the molecules are detected in aggregate during a detection step, wherein the site comprises at least two different types of molecules, wherein the molecules comprise nucleic acids; (b) means for detecting a signal corresponding to the aggregate of molecules comprising nucleic acids at the site; (c) means for providing an initial estimate of the amount of signal corresponding to each of the at least two different types of molecules comprising nucleic acids at the site; (d) means for calculating the amount of signal corresponding to each of the at least two different types of molecules comprising nucleic acids at the site using the initial estimate, thereby obtaining a signal estimate; and (e) means for iteratively updating the initial estimate until the signal estimates converge, thereby detecting molecules associated with the site.
