+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.

 # ATAC-seq Astrocyte Workflow
 
-<!-- TODO: Fill out intro (AS) -->
+ATAC-seq is a bioinformatics best-practice analysis pipeline used for ATAC-seq (Assay for Transposase-Accessible Chromatin using sequencing) data analysis. It is built upon the ENCODE ATAC workflow written in workflow description language (wdl) and uses Nextflow to run in the astrocyte platform.

 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`

+ * ATAC-seq is a molecular biology technique that assesses chromatin accessibility in a genome. It uses a hyperactive Tn5 transposase to insert sequencing adapters into open chromatin regions, allowing researchers to identify and sequence these accessible genomic regions. ATAC-seq is widely used to study gene regulation, identify enhancers and promoters, and gain insights into chromatin structure.
