Omics Dashboard
The Pathway Tools Omics Dashboard is a tool for visualizing omics data. It consists of a set of panels, each representing a system of cellular function, e.g. Biosynthesis. For each panel, we show a graph depicting omics data for each of a set of subsystems, e.g. Amino Acid Biosynthesis and Carbohydrates Biosynthesis. Each panel has its own y-axis, so that omics data for the different subsystems within a panel can readily be compared with each other. Multiple timepoints or experimental conditions are plotted as separate data series within the graph. Clicking on the plot for a given subsystem brings up a detail panel, breaking that subsystem down further into its component subsystems. At the lowest level, the values along the x-axis correspond to the individual objects in the dataset (i.e. genes for gene expression data, metabolites for metabolomics data, etc.).See the Omics Dashboard Help document for more information, or choose one of the links in the examples table below to see the Omics Dashboard in action on an example dataset.
See the Omics Dashboard without omics data to see the full set of systems, subsystems, and the genes that comprise them for the currently selected organism.

Invoke the Omics Dashboard
SingleOmics Datasets
Choose one of the following options to specify omics data for the Omics Dashboard:Your most recently uploaded omics dataset
Upload a tab-delimited file
MultiOmics Datasets
Supply two or three related datasets (e.g. transcriptomics and metabolomics, or transcriptomics, proteomics and metabolomics) to view them together on the Omics Dashboard. If three datasets are supplied, two of them will share a y-axis, so you may find it useful to normalize the data before submission.Performance Note: While uploading a large dataset to the dashboard may take some time to process initially, if you are experiencing ongoing performance issues while interacting with the dashboard, we recommend you try one of the following:
- We have found that performance tends to be best using an up-to-date version of the Chrome browser, as compared to Firefox or Safari. If you are not currently using Chrome, you may wish to switch browsers.
- If your dataset contains a large number of data columns (e.g. timepoints), try loading or displaying only a subset of them to reduce the amount of data that needs to be processed.
- If your dataset contains a set of replicate groups, with multiple data columns per group, try preprocessing your data in the spreadsheet and upload columns containing group averages only.
Omics Dashboard Examples
- 0-centered scale: implies that the numerical data of your file can contain positive and negative values. The value 0 is considered to be the center of the numerical values provided in your data file. Data in log ratio format are 0-centered.
- 1-centered scale: implies that any negative or zero values in your data file should be skipped. Moreover, the data is centered around the value 1. For example, the value 0.1 is considered to be at the same distance to 1 as the value 10. So, a logarithm of base 10 is applied to your data before the linear coloring mapping is applied.
For a time series or multiple conditions: enter a list of column numbers (each column number corresponding to a single timepoint), separated by spaces, a range of integers (e.g., 2-4), or both. Alternatively, use the wildcard * to specify all columns from 1 to the last column, or N-* to specify all columns from column N to the last column (e.g. 5-*). The number of columns in the file is determined by the number of columns in the first non-comment line in the file.
Important note: The first column of your file contains names and/or identifiers and is column number 0. The first potential numerical data column is column number 1.
