    started a topic NCBI SRA database

    NCBI SRA database

    Hello,

    Is someone familay with NCBI SRA database: http://www.ncbi.nlm.nih.gov/sites/entrez

    searching SRA for SRP000607 about Korean genome study, got 5 experiments,

    What's the relation about experiment, runs and spots?

    These 5 experiment sampled from the same person, all supposed to have paired reads, but SRX002757 does not have paired data.

    Under SRX002761, the reads files are strange to me, like:

    06/11/2009 12:00AM 239 SRR016027.fastq.gz
    06/11/2009 12:00AM 788,821,597 SRR016027_1.fastq.gz
    06/11/2009 12:00AM 797,621,364 SRR016027_2.fastq.gz
    06/11/2009 12:00AM 22,470 SRR016028.fastq.gz
    06/11/2009 12:00AM 809,891,610 SRR016028_1.fastq.gz
    06/11/2009 12:00AM 810,659,524 SRR016028_2.fastq.gz

    SRR016027_1.fastq.gz mates to SRR016027_2.fastq.gz, how about SRR016027.fastq.gz?

    I want to play with this datasets, can I just use all the paired files in these 5 experiments and ignore the unpaired files like SRR016027.fastq.gz?

    Lots experts here, any help will be appriciated!

    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...

    Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing
    by GATTACAT
    Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
