    How to decompress several fastq.gz files into one single file?

    How to decompress several fastq.gz files and concatenate them into one single .fastq file? There are two kinds of file in the same folder, some ending in ...R2_001.fastq.gz , and others ending in R1_001.fastq.gz. The work is to decompress and concatenate files ending in ...R2_001.fastq.gz into one R2_001.fastq file, and do the same for ...R2_001.fastq.gz files. Really appreciate any help. Thanks -madza

    gunzip decompresses gz files, cat concatenates them, and * is a wildcard. This is all in the Unix command line once you've moved to the directory with the files.
    gunzip *R2_001.fastq.gz
    cat *R2_001.fastq > combined_R2_001.fastq

      Code:
      zcat *R2* > concatenated_R2.fastq.gz
      zcat *R1* > concatenated_R1.fastq.gz

            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, detection...

            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
