 ### 1. Outline
 
 ASPEN or **A**tac **S**eq **P**ip**E**li**N**e is CCBR's pipeline to calls peaks for ATAC-Seq datasets. It currently accepts paired-end Illumina data and calls peak using [MACS2](https://doi.org/10.1186/gb-2008-9-9-r137) and [Genrich](https://github.com/jsh58/Genrich) peak callers. Below is a brief outline of the steps performed by the pipeline:
 
--   Trim PE reads with [CutAdapt](https://doi.org/10.14806/ej.17.1.200)
--   Remove reads aligning to known [blacklisted regions](https://doi.org/10.1038/s41598-019-45839-z), if provided
--   Align reads provided genome using [bowtie2](https://doi.org/10.1038%2Fnmeth.1923). This step generates multiple output files:
-    -   `tagAlign.gz`, which is a BED6 format file mainly required for MACS2 peak calling
-    -   `dedup.bam`, deduplicated BAM format file which may be required for downstream processing (eg. [TOBIAS](https://github.com/CCBR/CCBR_tobias))
-    -   `qsorted.bam`, query sorted BAM file for Genrich peak calling
--   Pre-peakcalling QC metrics:
-    -   [FastQC](https://www.bioinformatics.babraham.ac.uk/projects/fastqc/) is run pre- and post-trimming
-    -   Fragment length distribution is calculated using custom scripts
-    -   [Preseq](https://smithlabresearch.org/software/preseq/) is run to estimate library complexity
--   Post-peakcalling QC metrics:
-    -   TSS distributions are calculated for each replicate
-    -   FRiP (Fraction of Reads in Peaks) is calculated for each replicate
-    -   FRiPextra calculations are performed if _fripextra_ config files are supplied
-        -   Fraction of reads in DHS regions
-        -   Fraction of reads in promoter regions
-        -   Fraction of reads in enhancer regions
--   Peak calling: Peaks (NarrowPeak format) are called using MACS2 and Genrich. If multiple replicates exist per sample, consensus peaks are called (BED format).
--   Peak annotation: [ChIPseeker](https://doi.org/10.1093/bioinformatics/btv145) is used to annotate peaks if the genome is hg38/hg19/mm10
--   Motif enrichment: Motif Enrichment is calculated using [HOMER](http://homer.ucsd.edu/homer/) and [AME (MEME suite)](https://meme-suite.org/meme/doc/ame.html)
--   Report: [MultiQC](10.1093/bioinformatics/btw354) is used to generate a customized final HTML report
