    read count with multicov

    Hi,

    I am doing a gene expression analysis, I have a raw data of libraries of RNAseq (microRNAs) of 2 conditions and 11 replicates each one, I used multicov to obtain the reads count

    bedtools multicov -bams SRR1054203.gz.segemehl.sam.bam.sorted.bam.bam SRR1054204.gz.cutadapt204.cutadapt.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054205.gz.cutadapt205.cutadapt.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054206.gz.cutadapt206.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054207.gz.cutadapt207.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054208.gz.cutadapt208.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054209.gz.cutadapt209.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054210.gz.cutadapt210.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054211.gz.cutadapt211.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054212.gz.cutadapt212.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054218.gz.cutadapt218.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054217.gz.cutadapt217.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054213.gz.cutadapt213.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054214.gz.cutadapt214.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054215.gz.cutadapt215.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054219.gz.cutadapt219.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054220.gz.cutadapt220.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054221.gz.cutadapt221.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054222.gz.cutadapt222.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054223.gz.cutadapt223.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054224.gz.cutadapt224.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054225.gz.cutadapt225.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054226.gz.cutadapt226.fastq.segemehl.sam.bam.sorted.bam.bam SRR1054216.gz.cutadapt216.fastq.segemehl.sam.bam.sorted.bam.bam -bed results.out > conteo_mature_genome2

    I found for example, several time the mature hsa-miR-941 MIMAT0004984 with different hairpin names and some of them have the same coordinates, and they have the same number of reads count.

    I do not know if it possible to have the option of a window to aggregate nucleotides in order to merge read that starts with a few nucleotides of differences, but that belong to the same mature microRNA and report only one microRNA ID.

    I check the bedtools manual and have the windowsbed but with multicov it does not work, any idea?. I need to overcome this because when I use this table in edgeR or DESeq, it does not work with repeated ID:

    Thanks very much

    regards

    You can download from miRBase a file with only the mature miRNAs.

      Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
      by SEQadmin2



      Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

      Cancer Drug Resistance: The Lingering Barrier to Rising Survival
      by SEQadmin2



      Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

      There is no single reason why many patients don’t respond to treatment as expected. Cancer is...
