To assess ATAC-seq library quality based on enrichment of accessibility signals around Transcription Start Sites (TSSs), calculate the TSS enrichment score according to [ENCODE recommendations](https://www.encodeproject.org/atac-seq/) as a functional signal-to-background measure. ![](https://cdn.document360.io/1fc69f91-cf1e-45ab-bc51-4063eb80e37c/Images/Documentation/Figure 4 ATAC-seq Manual [success and opt table].jpg) **Figure** **1.** Success metrics and optimization guidelines. ![](https://cdn.document360.io/1fc69f91-cf1e-45ab-bc51-4063eb80e37c/Images/Documentation/image(25).png) F**igure 2.** Representative open chromatin profiles and QC metrics generated by a robust, well-established ATAC-seq workflow. Results demonstrate highly reproducible peak profiles, strong FRiP scores, and high TSS enrichment across experiments
