  • Troubleshooting: Nexseq run completed but status is "failed"

    Hi everyone. I prepped some samples with Nextera xt kit and run them on the next seq. I monitored the run and everything was fine until the uploading step. I can see cluster density, %pf and %q30, and in the run completion file it says CompletedAsPlanned. So I don't understand why in the status it says Failed. Can you guys help me troubleshooting? Seems like nothing has gone wrong.

    Sounds like you do your analysis in BaseSpace? Was there a network failure of some kind?

    Your best bet is to engage Illumina techsupport but someone else who uses BaseSpace may be able to help.

      I use basespace to monitor the run status remotely and also to download the fastq file because the nextseq machine is shared with other people so we use it just to set up the sequencing. I just don't understand why it stopped. I can actually see a fastq file generated but the size is small probably because it has data just for a few samples?

        This has happened to me with the MiSeq and it was a problem with the sample sheet that kept the run from demuxing. If this is what happened then the error log will tell you which lines of your sheet need to be fixed.

          Thank you jdk787. I have double checked the sample sheet and this is fine. I can't see any error log file, could you please remind me where to look for it please?

            Issue solved. There was a network failure so I requeued the analysis and now it's fine!!

              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...
