 ## The ATAC-seq Runner workflow
 <!-- TODO: Fill out intro to ATAC-seq pipeline. Which commands do we use to run this pipeline? What will the NextFlow script use? (AS) -->
 
+This pipeline is designed for automated end-to-end quality control and processing of ATAC-seq. The pipeline can be run end-to-end, starting from raw FASTQ files all the way to peak calling and signal track generation using a single caper submit command. One can also start the pipeline from intermediate stages (for example, using alignment files as input). The pipeline supports both single-end and paired-end data as well as replicated or non-replicated datasets. The outputs produced by the pipeline include 1) formatted HTML reports that include quality control measures specifically designed for ATAC-seq and DNase-seq data, 2) analysis of reproducibility, 3) stringent and relaxed thresholding of peaks, 4) fold-enrichment and pvalue signal tracks.

 On HPC, make sure that Caper's conf ~/.caper/default.conf is correctly configured to work with HPC. The following command will submit Caper as a leader job to SLURM with Singularity
 `caper hpc submit atac.wdl -i "${INPUT_JSON}" --singularity --leader-job-name ANY_GOOD_LEADER_JOB_NAME`
