Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for analyzing data from digital PCR experiments face challenges in visualizing and quantifying results, especially when dealing with rare occurrences, due to the complexity of handling large numbers of small sample volumes and the difficulty in distinguishing between positive and negative reactions.
Innovation Solution
A computer-implemented method and system for generating data visualizations using a graphical user interface, which includes displaying data points on a scatter plot indicative of nucleic acid amplification, allowing users to adjust thresholds to designate and alter designations of data points, and providing integrated views of chip thumbnails, cluster plots, and heat maps to enhance data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of reaction sites in a test or experiment is increased to provide greater numbers of reactions per test, then the productivity is improved, but the sample volume per reaction decreases and the data visualization and analysis becomes more complex
Solution Approach 1:
The patent segments the large dataset from high-throughput PCR experiments into multiple visual representations (scatter plots, heat maps, bar graphs) that can be independently analyzed. Each visualization type focuses on specific aspects of the data, making the overall analysis manageable despite the large number of reactions being performed simultaneously
Solution Approach 2:
The patent transforms complex multi-dimensional PCR data into multiple two-dimensional visual representations. By creating different types of plots (scatter plots showing fluorescence intensity, heat maps showing reaction patterns, bar graphs showing quantification), the system adds visual dimensions that make the complex data from numerous reactions easier to interpret
2Measurement precision
If the sample volume is reduced to enable digital PCR with smaller sample volumes containing zero or one target nucleotide sequence, then the measurement precision is improved for rare allele detection, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent uses color-coded visual representations to indicate different outcomes of PCR reactions. Heat maps use color intensity to represent fluorescence signal strength, scatter plots use color to differentiate between positive and negative reactions, and bar graphs use color to indicate quantification levels. This visual encoding makes it easier to detect and measure rare positive reactions among many negative ones
Solution Approach 2:
The patent creates multiple visual copies or representations of the same underlying data. Instead of presenting raw numerical data from digital PCR, the system generates multiple visual copies in different formats (scatter plots, heat maps, bar graphs), each highlighting different aspects of the rare allele detection, making the data easier to interpret and quantify
3Ease of operation
If integrated views of chip thumbnails, cluster plots, and heat maps are provided to enhance data analysis, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple types of visualizations (chip thumbnails, cluster plots, heat maps, bar graphs) into a single integrated user interface. These different visualization types are combined in a coordinated manner where they all display data from the same underlying dataset, allowing users to analyze PCR results comprehensively in one view rather than switching between separate tools
Solution Approach 2:
The patent creates a multi-functional visualization system that can display multiple types of data representations simultaneously. The same system generates scatter plots for initial data viewing, heat maps for pattern recognition, bar graphs for quantification, and chip thumbnails for overview, making the system universally applicable to different stages of data analysis without requiring separate specialized tools

AI summary
In some embodiments, a method or system for visualizing data generated from one or more reaction devices, chips, or reaction sites may be provided. On a scatter plot, data points may be displayed indicative of results from nucleic amplification, wherein the nucleic acid amplification comprises a first target and a second target and the data points are designated as being indicative of amplification of the first target, the second target, both targets, or neither target. In response to user input, an adjustable threshold may be varied used to designate the data points. And, in response to the varying, designations and a display of the designations may be altered for one or more of the data points whose designation is changed based on the varied threshold.
