I am having trouble using skewer and I could use some help. I will wait to see if this thread is still active before going into the issue.
Thanks.

Hi all
I was able to get the issue figured out before posting my question. I am new to Skewer and it seems SO flexible that there are almost too many parameters to keep track of and to get the right combination of them working to get the right answer is a challenge.
In short, the problem I was having was that I was not using the correct -m setting for what I was trying to do. All I wanted to do was trim the primer sequence from the beginning of some paired-end MiSeq reads. The problem was that I kept trying to use the -m pe since these were paired-end reads. I had tried the -m head, but using just the individual sequence primer fna files, and it only worked for the R1 reads, but would not properly trim the R2s. I was finally able to get what I wanted using -m head, and referencing both the forward and reverse primer sequences as well as both the R1 and R2 together.
% skewer -m head -f solexa -x SM_V4_forward.fna -y SM_V4_reverse.fna Sample_R1_filtered.fastq Sample_R2_filtered.fastq -o Sample_filtered
Thanks again for your offers to help.

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...-

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...-
