Has anyone compared ATAC run as PE vs SR? Everyone requests PE but why is that more necessary than, for example, with ChIP or FAIRE?

Frankly, a lot of people request PE for a lot of applications where it won't help, because they don't know what they're doing and it sounds like more bang for your buck (twice as many reads! /s).
For a good time, take some 2x100 data and see how different your results are if you rerun your pipeline with only read 1, or even with only the first 50 nt of read 1. For vertebrate genomes I find minor differences in alignability between 1x50 and 1x100, and very little difference between 1x100 and 2x100. -
Better mappability (particularly in repeats), better estimation of fragment size? We just did what jwfoley suggested with a PE ChIP library and turns out that fragment estimation was shot at <5M reads using only read 1.Comment

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...04-22-2024, 07:01 AM -
Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...04-04-2024, 04:25 PM
