What is HAP file?
HAP is a text file format. It contains several meta-information lines followed by ## , one line containing only the # sign, one header line, and those data lines. Each data line contains the information for one SNP， including the chromosome ID, the position of the SNP in the chromosome, the rs ID, and the haplotypes of each individual.

What are the common issues of the input files?
1) File size. We require that each file is not larger than 1 G;
VCF check: validity + statistics such as #samples, chromosomes, SNPs, chunks, phased / unphased, reference build.
Quality control statistics: duplicate sites, SNPs removed, NonSNP sites, monomorphic sites, MAF check.
What is the data security?
The data will be transferred to our server, a wide array of security measures are enforced:
The complete interaction with the server is secured with HTTPS.
All results are encrypted with an one-time password, thus only you can get them.
