  • dbNSFP: dbNSFP is a database developed for functional prediction and annotation of all potential non-synonymous single-nucleotide variants (nsSNVs) in the human genome.

  • dbscSNV: dbscSNV includes all potential human SNVs within splicing consensus regions (−3 to +8 at the 5’ splice site and −12 to +2 at the 3’ splice site), i.e. scSNVs, related functional annotations and two ensemble prediction scores for predicting their potential of altering splicing. Currently dbscSNV serves as an attached database for dbNSFP.

  • WGSA: WGSA is an annotation pipeline for human genome re-sequencing studies, to facilitate the functional annotation step of whole genome sequencing (WGS). Currently WGSA supports the annotation of SNVs and indels locally without remote database requests, allowing it to scale up for large WGS studies.

Population Genetics

  • SRV: srv is a forward simulation algorithm, which simulates DNA sequences assuming realistic models for human demographic and natural selection.

  • jPopGen Suite: jPopGen Suite is an user-friendly package of java programs for population genetic analysis of SNP spectrum data from randomly sampled DNA sequences.
  • Stairway plot: The stairway plot is a method for inferring detailed population demographic history using the site frequency spectrum (SFS) from DNA sequence data. It does not need a pre-defined population model and can be applied to hundreds of unphased sequences.
