  • fastq-dump errors

    I'm getting two errors on certain fastq-dump jobs. I am submitting jobs to HTCondor using a dag file to manage downloads. I am queuing multiple jobs and sometimes I get the following errors:

    2016-03-31T03:17:24 fastq-dump.2.5.7 err: file unauthorized while opening file within network system module - log failure: RC(
    rcText,rcString,rcConverting,rcBuffer,rcInsufficient) in 'error with http open '$(U)''
    2016-03-31T03:17:24 fastq-dump.2.5.7 err: item not found while constructing within virtual database module - the path 'SRR0593
    27' cannot be opened as database or table

    The strange thing is that sometimes I get the errors and sometimes I don't, even for the same files. For instance if I download 10 files, and 5 return these errors, if I submit the same ten jobs again, some or all of the files which gave errors might download normally. I'm very confused about this, any suggestions would be great. (I think the second error is the result of the first because these files seem to exist.)

    If it's any consolation we gave up trying to understand all of the fastq-dump errors we saw and we now have a loop in our pipeline which simply tries the command again (up to 5 times) before deciding that there really is an error. a scary number of fastq-dump errors are not reproducible :-(

      Current Approaches to Protein Sequencing
      by seqadmin


      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

      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...
