    There's no practical difference between merging the fastq files or merging the SAM files. One could argue that if these are paired-end reads, then the SAM files should be merged in case you use an aligner that re-estimates insert size (this could be different if the second sequence batch comes from a different library prep), but that's not terribly likely to create a big issue.

    union of two sequencing fastq files

    Dear All,

    I just received some MeDIP sequencing data.
    Out of 4 samples, one is really low in total reads number.
    Due to this the service will provide me some additional reads (resequencing the sample) to compensate this difference.

    A naive question, is it correct to merge the two fastq files, or I better merge the sam files? or is the same?

    Thanks,
    Paolo

    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...
