Imputing small region of the genome
If I'm looking for a specific SNP in my SNP-Chip data and it isn't there, are there any tools that let me quickly impute that SNP from surrounding SNPs rather than running a lengthy 'whole chromosome' ...

Given SNP-Chip data for a population, what tool should I use to reconstruct haplotypes?
I think Eagle or haploSep will do the job of reconstructing haplotype data, but I'm not sure what the 'standard' or best practice tool to use is.
I have a VCF/PLINK format file of ~8,000 individuals ...

How do I infer someone's haplotype of a gene from data on several of the gene's SNPs?
For a a few SNPs from given gene, I know there happen to be several haplotypes that most of the population has. But from a person's data on those SNPs, we have two alleles at each SNP, so it's not ...

Genotyping technologies do not maintain phase?
Why exactly does genotyping not maintain phase? I guess I'm more confused on what's the difference between sequencing and genotyping, and as a result how phase is maintained in one, but not the other. ...
