Data preparation and quality assurance are arguably the most important aspects of genome-wide association studies...and definitely the most arduous. Your choice of methods can be the difference between success or failure. But with hundreds of new methods published each year, how do you know which to employ for a given study and ascertainment condition?

Join us for Part 3 of this educational webcast series as Dr. Lambert examines a number of effective data prep and QA methods that will help you get more meaningful results without all the headaches.

Topic include:
  • SNP-Based Sample QC (call rates, X heterozygosity, Nsp-Sty mismatches, cryptic relatedness and contamination, population stratification)

  • CNV-Based Sample QC (derivative log ratio spread, wave effects, outliers, cell line artifacts, segment over/under abundance, gender check)

  • Correcting Batch Effects and Population Stratification

  • SNP Filtering

Register today and learn how you can achieve genome-wide success with the latest in data prep and quality assurance methods.
