Hi I'm in need of some help. I need to find a motif with an ambiguous amino acid among sequences that range from 4 to 18 million long. I have a computer with 128 gb of RAM using Windows 7 and I've run motif searches with the programs CLC and Geneious, however, they take too long as they are very processor heavy. I initially tried blast, however, I found that blast does not do well with ambiguous amino acids. Any input would be greatly helpful!

Originally posted by Minkyu View PostThanks! However, after reading the instructions I found that it was CPU intensive not RAM intensive. Do you have any programs that runs primarily on RAM?
Thanks,

The only thing you could do is run the search on a cluster, and partition the search items across multiple nodes (ie. each compute node only searches for a subset of the total sequences in your search set), so no one node has to bear the entire computational load.Michael Black, Ph.D.

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...-
