I am doing some experiment using BowTie and WHAM which are short read aligners that aligns short DNA sequences (reads) to the human genome. In WHAM, it is specified that for 75 bps reads, it is biologically required to allow matching with two errors and if the read length increases, allowed mismatch errors should increase. Now, I want to experiment with those two tools on 150 bps. Can anybody help me what should be the allowed matching errors for 150 bps or where can I find information about it ? Actually, I want information about, "maximum tolerated miss match errors" which is biologically relevant or for various (specially 150 bps) read length. I became confused because of this list of aligners, which has varied "maximum tolerated miss match errors". Can anybody please help me about this ? Thanks in advance.

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 -
Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...03-22-2024, 06:39 AM
