Explanation of Public Analysis Results

• This page contains all public analysis results submitted through the exRNA Atlas analysis tools.
• These results are available to everyone and cover much of the Atlas data.
• They should be useful for an initial examination of what the Atlas has to offer.
• Use each Click to View link to view the results associated with a given analysis.

List of Tools

Below, you can read more about the different analysis tools offered by the exRNA Atlas.
Currently, all analysis tools work solely with RNA-seq profiles.

Deconvolution (Currently Only Available for Public Analyses)

• Download an archive containing the results of the deconvolution analysis.
• Result files include:
  • Stage 1 Deconvolution
  • Heatmap representing the correlation between the deconvoluted cargo profiles modeled for the current dataset and the cargo types (CT) estimated from the deconvolution of individual Atlas datasets across informative ncRNAs.
  • Table of estimated constituent cargo profiles across 20,000+ ncRNA [miRNA, piRNA, tRNA, Y RNA, lincRNA, snoRNA, snRNA] transcripts (expression is normalized to [0:1] range).
  • Heatmap representing the proportions of each cargo profile for each sample in the current dataset.
  • Table of estimated proportions of each cargo profile for each sample in the current dataset.
  • Boxplots representing the proportions of each cargo profile for each sample in the current dataset separated based on provided metadata features.
  • Stage 2 Deconvolution
  • Tables of estimated average cargo profiles across 20,000+ ncRNA (miRNA, piRNA, tRNA, Y RNA, lincRNA, snoRNA, and snRNA) transcripts in reads per million (RPM) separated based on provided metadata features. Tables include mean expression, std. errors, degrees of freedom, and per sample residuals.
• Tool designed and implemented by Oscar Murillo at the Bioinformatics Research Lab, Baylor College of Medicine, Houston, TX.
• Integrated into the exRNA Atlas by William Thistlethwaite at the Bioinformatics Research Lab, Baylor College of Medicine, Houston, TX.

DESeq2

• View a table containing differentially expressed miRNAs for selected Atlas data.
• Sort data by a variety of different metrics (adjusted p-value by default).
• Select some subset of miRNAs and use the Pathway Finder tool to find pathways containing miRNAs of interest (or protein targets of those miRNAs).
• Currently, our integration of the tool allows for pairwise comparisons of sample profiles (two conditions, two RNA isolation kits, etc.).
• Tool designed and implemented by Michael Love, Simon Anders, and Wolfgang Huber (PubMed).

Dimensionality Reduction Plotting Tool (Currently Only Available for Public Analyses)

• Visualize selected Atlas data via PCA and tSNE embedding.
• Choose between three different plotting styles (ggplot2, plotly 2D, and plotly 3D).
• Pick between four different RNA categories (miRNA, piRNA, tRNA, snRNA) for your visualization.
• Color your plots by various metadata categories like dataset, anatomical location, condition, and biofluid name.
• Use filters to add or remove different datasets and biofluids from a given plot (with dynamically adjusted counts for each option).
• Note that these filters are purely visual and do not recompute the PCA or tSNE values.
• Tool designed and implemented by James Diao and Joel Rozowsky at the Gerstein Lab, Yale University, New Haven, CT.
• Integrated into the exRNA Atlas by William Thistlethwaite and Andrew R. Jackson at the Bioinformatics Research Lab, Baylor College of Medicine, Houston, TX.

Generate Summary Report

• Download an archive containing a collection of summary files describing the output from exceRpt for selected samples.
• Summary files include:
  • Plots including read count distributions, biotype distributions, miRNA abundance distributions, etc.
  • Read count tables for each library (miRNA / tRNA / piRNA / etc.) that span all selected samples. Both raw counts and normalized counts (reads per million mapped reads) are available.
  • Visualized taxonomy trees for exogenous rRNA and exogenous genomic reads.
• A full list of summary files can be found on the exceRpt Tutorial Page.
• Tool designed and implemented by Rob Kitchen and Joel Rozowsky at the Gerstein Lab, Yale University, New Haven, CT.
• Integrated into the exRNA Atlas by William Thistlethwaite and Neethu Shah at the Bioinformatics Research Lab, Baylor College of Medicine, Houston, TX.
