    Hi Shi,

    how to do the same on linux? I want reads mapped to rRNA regions. how to do that? I have gtf and bam file.

    In featureCounts manual it is given.

    featureCounts -p -t exon -g gene_id -a hg19_RefSeq.gtf -o counts.txt accepted_hits.bam

    This Summarize paired-end reads and count fragments (instead of reads).

    Is this right one to count read pairs mapped to rRNA regions. Could you please help me.

    Thank you

    It accepts both SAM and BAM format input files. By default, it assigns reads to NCBI RefSeq exons and/or genes. But you can provide your own annotation.
    Hi Shi,
    Thank you for your help.

    Dear all, I also want to know how to count reads mapping to different regions of one gene. Could any one do me the favor? Thanks!

  • How to count the reads mapping to different regions from tophat output

    Hi All.

    I just mapped the RNA-Seqs by Tophat and got the output file accepted_hit.bam. I want to count the reads mapping to different regions such as exon,intron,exon-exon junction,exon-intron junction intergenic,rRNA and so on. I am really new in this field. Is there any software or custom script can do this? If you have a script can do this, would you please share it with me?Thank you very much.

    Any reply will be appreciated.

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    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...

    Current Approaches to Protein Sequencing
    by seqadmin


    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...
