Introduction
RankU is a comprehensive AI tool designed to assist researchers in the field of genomics and bioinformatics. It offers a robust platform for conducting rank product or rank sum analysis, which is crucial for identifying differentially expressed genes across various studies. The tool is equipped with a user-friendly interface that allows for seamless data input, analysis, and result interpretation. It supports both one-class and two-class analysis, making it versatile for different types of experimental designs. RankU also provides advanced features such as the ability to combine data from different studies, enhancing the power of gene expression analysis.
background
RankU is built on the foundation of the Rank Product method, a well-established technique in the field of genomics. The method was developed to address the challenges of identifying differentially expressed genes in replicated microarray experiments. RankU takes this a step further by incorporating AI algorithms to enhance the analysis process, making it more efficient and accurate.
Features of RankU
Data Analysis
RankU can analyze datasets where each row corresponds to a gene and includes class labels for samples.
Log Transformation Support
The tool supports log transformation of data, with an option to specify whether the data has been previously log transformed.
Missing Value Handling
It handles missing values by replacing them with the genewise median of non-missing values, with an option to specify the minimum number of valid pairs.
Gene Names Attachment
Gene names can be attached to the outputs if provided, enhancing the readability of the results.
Plotting Functionality
RankU offers plotting functionality to visualize the estimated percentage of false positive predictions (pfp) versus the rank of each gene.
Random Number Generator
A reproducible state for the random number generator can be set if specified, ensuring the reproducibility of results.
Rank Product Method
By default, the rank product method is performed, but the rank sum method can also be chosen, providing flexibility in analysis approaches.
Advanced Analysis Options
Advanced analysis options are available, including the ability to combine data from different studies and handle multiple origins.
How to use RankU?
To use RankU, start by preparing your gene expression data with appropriate class labels. Input the data into RankU and specify whether the data has been log transformed. Set the missing value handling parameters and optionally attach gene names. Choose between the rank product or rank sum method and initiate the analysis. View the results, including the estimated pfp, p-values, and rank statistics, through the built-in plotting tool.
