Interactive HTML5 visualization for CRISPR/Cas9 knockout screen experiments.
VISPR is a web-based, interactive visualization framework for CRISPR/Cas9 knockout screen experiments.
The easiest way to install VISPR is to use the Miniconda Python distribution (http://conda.pydata.org/miniconda.html). We recommend to use the Python 3.4 variant. With miniconda installed, you can issue
conda install -c liulab vispr
to install or update VISPR with all dependencies. If you are using an old version of MacOS X and the conda command is not available after installation of Miniconda, you have to change your shell to bash. To do this permanently, issue
chsh -s /bin/bash
After successful installation, you can test VISPR with example data by executing
VISPR takes [MAGeCK](http://liulab.dfci.harvard.edu/Mageck) and [FastQC](http://www.bioinformatics.babraham.ac.uk/projects/fastqc) results as input. These are provided along with additional parameters as config files. One config file defines one set of results (i.e. one experiment). VISPR can be invoked with multiple config files (i.e. multiple experiments), allowing to select and compare experiments via the user interface. The easiest way to generate your own data for visualization in VISPR is to use the [MAGeCK-VISPR](https://bitbucket.org/liulab/mageck-vispr) workflow. For manual creation of a VISPR config you can issue
to obtain a template for modification. Once you have a config file (either generated by the workflow or manually, you can issue
vispr server path/to/config.yaml
to start a server process that renders the VISPR user interface in a webbrowser.
Installing VISPR with another Python distribution (for experts)
Make sure that you have numpy, scipy, scikit-learn and pandas installed. Else, their automatic compilation with the command below would take very long. Then, you can issue
pip install vispr
pip install vispr –user
if you want to install VISPR without admin rights. All remaining dependencies will be installed automatically.
