PROGRAM NAME - D_stat_0.6.cpp
DESCRIPTION - C++ implementation of D_stat_0.6.py by James Cahill
""
This version is for fasta files, they should be aligned and ordered correctly
If you want to calculate this D stat: D(Indiv1,Indiv2,Admix,OG)
Input is as follows:
python D_stat_0.5.py Indiv1.fa Indiv2.fa Admix.fa OG.fa block_size > D_I1_I2_Ad_OG.dstat
""
