       Segmented  HAPlotype  Estimation  and  Imputation  Tools  version  4  (SHAPEIT4).  SHAPEIT4 is a fast and
       accurate method for estimation of haplotypes (aka  phasing)  for  SNP  array  and  sequencing  data.   It
       includes  a  Positional  Burrow  Wheeler Transform (PBWT) based approach to quickly select a small set of
       informative conditioning haplotypes to be used when updating the phase of an individual.  It accounts for
       sets of pre-phased genotypes (i.e. haplotype scaffold).  The scaffold can be derived either  from  family
       data  or  large  reference  panels.  It reads and writes files using HTSlib for better I/O performance in
       either VCF or BCF formats.  The genotype graph and HMM  routines  have  been  re-implemented  for  better
       hardware usage and performance.
