I have now automated the process and can do "quick and dirty" statistics of all below listed populations. Adding new populations takes about two days in a case I have them in my backbone data base. Here are now existing populations and sample counts. Adding new populations to my data base takes longer, around a week.
The results are based on slightly changed phasing parameters, so there can be slight differences in absolute values. Used programs are Plink, Impute2 and Beagle version 5.
