B) Method2 For macOS  platform INSTALL
	you should  must  pre-install the library [zlib] and copy them to the corresponding library directory
	#step1 :Should must <b>re-install</b> the gz library [zlib]
			  see  [zlib] website 
	#step2  :  # Copy these gz library file into the corresponding library directory
			  cp libz.a libz.so*  PopLDdecayXX/src/include/zlib
	#step3  : 
	          sh make.sh # or [make && make clean]

C) Other Method
Note if it can't work . follow below  B1-B6  or use the  static Compiled [BamDeal_Linux ]

查看PopLDdecay的使用方法

sample:

# 1)  For gatk VCF file deal , run PopLDdecay  direct
          ./bin/PopLDdecay    -InVCF  SNP.vcf.gz  -OutStat Lddecay.stat.gz   
# 2)  For plink [.ped .map], chang plink 2 genotype first  2) run PopLDdecay  
           perl bin/mis/plink2genotype.pl    -inPED in.ped -inMAP in.map  -outGenotype out.genotype ;      ./bin/PopLDdecay        -InGenotype out.genotype -OutStat LDdecay.stat.gz 
# 3)  To Calculate the subgroup GroupA LDdecay in VCF Files   # put GroupA sample names into GroupA_sample.list file
          ./bin/PopLDdecay   -InVCF    -OutStat    -SubPop    GroupA_sample.list
