I have a graphic that show an increase in coverge of A over T, and It increses until the end sequence, in all lanes of paired ends runs of 72 pb. Can GAIIx introduce a bias in coverage A on T?

An older dataset (of lower quality) of our is different, with C considerably over G, and T slightly over A.
I don't know if this is an effect from the base-caller or if it's from the adapter sequences, but it's there, around 1% difference. How much of a gap are you seeing?Last edited by tonybolger; 05-18-2011, 04:09 AM.

I guess if you're only seeing it in genomic data, it could be related to the specific adapters used.

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...-

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...-
