Notas do Editor

  • The basic research process remains essentially unchanged since the emergence of the scientific method in the 17th Century.
    Collect data, analyze data, identify patterns within data, seek explanations for those patterns, collect new data to test explanations.

    Speed of discovery depends to a significant degree on the time required for this cycle. Here, new technologies are changing the research process rapidly and dramatically.
    Data collection time used to dominate research. For example, Janet Rowley took several years to collect data on gross chromosomal abnormalities for a few patients. Today, we can generate genome data at the rate of billions of base pairs per day. So other steps become bottlenecks, like managing and analyzing data—a key issue for Midway.

    It is important to realize that the vast majority of research is performed within “small and medium labs.” For example, almost all of the ~1000 faculty in BSD and PSD at UChicago work in their own lab.
    Academic research is a cottage industry—albeit one that is increasingly interconnected—and is likely to stay that way.
  • Given continued exponential growth along so many dimensions …
    … process efficiencies must improve at a comparable rate to maintain just constant progress

  • Highlight CI Connect; coming up in Rob Gardner’s talk
    Highlight XSEDE’s planned adoption of user, group and profile management
  • Our goal is to operationalize key capabilities so researchers can depend on them. Think of Gmail for science..
  • We built this pipeline to create high quality variants using multiple genotyping algorithms
  • Applying previous pipeline to targeted exomes in breast cancer. http://abstracts.ashg.org/cgi-bin/2014/ashg14s.pl?author=madduri&sort=ptimes&sbutton=Detail&absno=140122328&sid=84013
  • Normal/tumor – for 2 subjects (form Geo, south Korean population)
     
    Run workflow on each normal and tumor and publish
     
     
    Qc, alignment, feature count, alignment qc  QC files, alignment file, and count file.
     
    Differential expression

    Picture shows how the gene EGFR expresses in lung and cancer tumor samples we have analyzed. We can do very similar analysis for ADNI, PPMI and other data sources easily.
