Uncolored nodes are not overrepresented, but they are the parents of overrepresented categories further down. Finally, a visualization of the overrepresented GO categories is created in Cytoscape. The program will inform you of its progress while parsing the annotations and calculating the tests, corrections and layout.
Finally, select a directory to save the output file in (the file will be named test.bgo if you filled in test as a cluster name), and press Start BiNGO.
#Cytoscape tutorial code
We want to consider all evidence codes, so don't fill in anything in the evidence code box. Select GO_Biological_Process from the ontology list, and Saccharomyces cerevisiae from the organism list. We're interested in assessing the overrepresentation of functional categories in our cluster with respect to the whole yeast genome, which is why we choose the Complete Annotation as the reference set. Since we only want to visualize those GO categories that are overrepresented after multiple testing correction, and their parents in the GO hierarchy, select the corresponding visualization option. Then select a statistical test (the Hypergeometric Test is exact and equivalent to an exact Fisher test, the Binomial Test is less accurate but quicker) and a multiple testing correction (we recommend Benjamini & Hochberg's FDR correction, the Bonferroni correction will be too conservative in most cases), and choose a significance level, e.g. The corresponding boxes are checked accordingly by default. We want to assess overrepresentation of GO categories, and we want to visualize the results in Cytoscape. Check the box Get Cluster from Network (see below for an example with text input). This name will be used for creating the output file and the visualization of the results in Cytoscape. Start by filling in a name for your cluster.
#Cytoscape tutorial install
I strongly recommend to use Docker to run your notebook server, but if you want to build on your machine, install the following to try these notebooks:Īgain, if you use the Docker container we provide, you don't have to install any of these.The BiNGO Settings panel pops up. Docker is a powerful tool to make your workflow reproducible, but it is not the main forcus of this course.
#Cytoscape tutorial software
About DockerĪll required software packages to run these lessons are packed in Docker container for your convenience. Building simple data analysis workflows requires only basic knowledge of Python. You don't have to worry too much about Python. Cytoscape data types - Networks, Tables, and Styles.Basic Python skill - only basics, such as conditional statements, loops, basic data types.Embed interactive visualization using cytoscape.js widget.Data visualization with IPython Notebook and Cytoscape.This tutorial is designed to learn the following topics:
In this tutorial, we will use IPython Notebook as an electronic lab notebook for your data analysis and visualization workflow with Cytoscape. Python is a perfect programming language for this purpose. This means there is a need to glue multiple tools and make them work nicely together to visualize complex data sets. In fact, there is no one-size-fits-all type tool for modern biology. However, no one can complete their data visualization workflow only with a tool. Welcome to the Advanced Cytoscape tutorial session! Cytoscape is a powerful tool for biological network data analysis and visualization and it is a de-facto standard tool in systems biology community.
