Question: What if I break my VCF file into small VCF files and then generate Haplotype indivually and merge it for calculation of dn/ds calculation ?

have VCf file which contain 1500 SNPs. Due to computational limitation , it is not possible for generating Haplotypes using PHASE program.

What if I break this VCF file into 5 separate VCF files and run the PHASE program individually and later on merging all the haplotype 2gether.

Is that a good idea or i just concentrate on SNPs which are present in the coding region of the genes.

Thanks in advance

Use another phasing program like beagle, fastPhase, mach, shapeit2, etc. They trivially work with 1500 SNPs. I would start from beagle or shapeit2.

Sir, I am trying to generate Haplotype file using beagle software using VCF file. But getting error. I have followed their tutorial but still stuck. even My .map file corresponding to VCF is returning error. Sir , Can you help me with small input files and command line . Thanks in advance
