WinHAP2.0 is an important improved version of WinHAP1.0.
(1) It runs much faster than WinHAP1.0 because it can be run with multiple cores.
(2) It can phase much larger datasets than WinHAP1.0.
(3) It can phase genotype sequences of arbitrary length with constant memory.

WinHAP1.0 is a fast haplotype phasing program for phasing large-scale population genotypes data.
(1) It can phase large-scale genotypes data in high speed.
(2) It outperforms most other programs in accuracy.
