    coverageBed using paired-end fastq as input

    I am new to Illumina data with more experience with Ion Torrent data. Recently, I have some fastq files and before:

    CoverageBed using a bam:
    Code:
     coverageBed -d -a targets.bed -b IonXpress_.bam > IonXpress_output.txt

    Now that I have 2 paired-end fastq files:
    S5_R1.fastq
    S5_R2.fastq

    How do I use them with coverageBed? Thank you .

    And you are back

    You seem to have overlooked the step of having to trim/align the fastq files to get an alignment file (BAM) before you can think about coverageBed.

      I am totally new to Illumina data and admit I did not think of that step. Do you have any recommendations far as what to use or where to begin? Thank you .

        What kind of data is this? I will suggest starting with BBDuk (to trim data/look for adapters) and then BBMap (to align) but other aligners will work as well.

          This is Illumina paired-end data from a NextSeq. I will give those to applications a try. Thank you .

            Is it DNAseq, RNASeq, ChIP_seq .. "what-seq" kind of data. BBMap would work for all of those but downstream analysis will be different.

              It is DNA-seq data. Thank you .

              I spent some time reading and learning some programing. Thank you for your helpful posts

                16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
                by SEQadmin2





                NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...

                Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
                by SEQadmin2



                Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

                Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
