  • SRA - SRR*.lite.sra

    Dear group,

    I have a question about .lite.sra files.

    For instance in a study there are 4 experiments (4 different SRX entries).

    In each SRX entry, there are different number of SRR.lite.sra files.

    for example SRX0001 there are 3 different SRR1.lite.SRA to SRR3.lite.SRA

    Are these 3 different runs (meaning 3 different fastq files) or you combine 3 lite.SRA files into one fastq file.

    What should be done. Please help.
    thanks
    Adrian

    Can you provide the actual accession number? Answer may be different depending on whether the data are from a multiplexed run or not.

      In a data set I recently looked at, each SRR-lite file was from a different subject, and the SRX files appeared to be (454) instrument runs. So there were 5 SRXs and about 300 SRRs. I am not sure if that is a general phenomenon, but you hopefully can tell what is what by using the run browser.

      It depends on what you want to do with the data. I didn't care about the individual subjects or runs and just wanted everything together.

        Strategies for Sequencing Challenging Samples
        by seqadmin


        Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
