SeqSIMLA can simulate sequence data in families with multiple affected and unaffected siblings or unrelated case-control under different disease models. Two disease models (the prevalence and population attributable risk models) are provided in SeqSIMLA. Alternatively, a penetrance table can be provided directly to SeqSIMLA. SeqSIMLA can also simulate quantitative traits while accounting for correlations in families.

Recent Update(2017/08/31): Bug fiexed. see more in change log.

New features:

  • Run SeqSIMLA online. Sign up and run...
  • Simulate disease and/or quantitative traits
  • Simulate unrelated case-control and/or family data
  • Accept user-specified pedigree structures
  • Simulate correlated quantitative traits considering shared environmental effects in families
  • Accept user-specified penetrance tables for the disease model, which allows for simulating gene-gene interactions
  • Exact simulation for disease status.
