    Picard MergeSamFile Memory Increase

    Does anyone know how I can increase the memory allowance of Picard MergeSamFile? The current one always use around 2 to 3G, no matter how much memory the machine actually has... And I can't find any parameter in Picard MergeSamFile that control the memory...

    Wondering whether MergeSamFile is faster with more than 3G memory too...

    Thanks!

      Pass -Xmx XG to your virtual machine where XG is the amount of memory you want
      to use.

      Also, use the multithreading option (USE_THREADING=Boolean) that has been recently added to picard. That should increase the performance by 20% (From the picard docs).

          16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
          by SEQadmin2





          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,...
