PEPATAC: a modular pipeline for ATAC-seq data processing
PEPATAC is a robust pipeline for Assay for Transposase-Accessible Chromatin using sequencing (ATAC-seq) built on a loosely coupled modular framework. It may be easily applied to ATAC-seq projects of any size, from one-off experiments to large-scale sequencing projects. It is optimized on unique features of ATAC-seq data to be fast and accurate and provides several unique analytical approaches.

Interactive job
Interactive jobs should be used for debugging, graphics, or applications that cannot be run as batch jobs.
Allocate an interactive session and run the program. Sample session:
