We're very happy with Silver level. Also echoing that I wouldn't attempt to run a next-gen system of any flavor without a service contract.

illuminaGA - Are these runs SR or PE? We are running PE and the strange observation is that Cycle 1 is good, Cycles 2-67 are poor, Indexing Cycles are good (and we get good multiplex efficiency), and Read 2 Cycles (another 67) are good. Illumina Tech Support is surprised that only Read 1 is affected. Do you have any similar data? Or are you only running SR?

Hi,cdalgard
I run PE(101+7+101). I stopped all the 3 test running around cycles 20. I didn't try finishing the running because the intensities form cycles 2-20 usually under 100k.

cdalgard- Hi, the "cycle2 issue" happened on our another GAiix. Same issue on our two marchine, that make me crazy
.
This time, the lot No. is 9303701 and 9303702

update-
I re-Hyb the flowcell and rerun. The new running performance well. I really want to figure out what happened.

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...-

Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...-
