With its increased popularity, experimental biologists frequently acquire large sequencing datasets for which they often do not have an easy analysis option. While a few bioinformatic tools are available, their installation and use typically require bioinformatic expertise. To make sequencing data analysis more accessible to a wide range of scientists, we developed a Platform-independent Analysis of Pooled Screens using Python (PinAPL-Py), which we present as an intuitive web-service. PinAPL-Py implements state-of-the-art tools and statistical models, assembled in a comprehensive workflow covering alignment, quality control, enrichment/depletion analysis and gene ranking. The workflow supports multiple libraries, and offers different analysis options for read count normalization or gene-ranking methods. Other technical parameters can be easily adjusted to allow greater flexibility and customization. Thus PinAPL-Py provides high-quality data analysis in an easily accessible service.Availability and implementation PinAPL-Py is freely accessible at pinapl-py.ucsd.edu with instructions, documentation and test datasets. Experienced users can run PinAPL-Py on their local machine using the Docker image (oncogx/pinaplpy_docker).
