  • 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

            Exploring the Dynamics of the Tumor Microenvironment
            by seqadmin




            The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

            Exploring Human Diversity Through Large-Scale Omics
            by seqadmin


            In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
