I have 8GB of RAM per job/slot I run on our cluster. So when I submit -p 8, I enable 64GB of RAM since I also open 8 slots then.

Tophat2 error
Hello, everyone,
I am a newer to use Tophat2/bowtie2 to align illumina paired-end RNA-seq, and a error occured as
No such file or directory.
Can someone help out to solve this problem? thanks,
Chanwu
command used:
tophat -o 81MAGABXX_5PE hg19 /media/sf_F_DRIVE/finished/81MAGABXX_5_R1.fastq /media/sf_F_DRIVE/finished/81MAGABXX_5_R2.fastq

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 on Modified Bases...-

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...-
