From paper, I have known that the genotyping of the ROS and MAP subjects was performed on the Affymetrix Genome-Wide HumanSNP Array6.0 (n = 1,709) and the Illumina OmniQuad Express platform (n = 384). And the genotypes were imputed using BEAGLE software. Therefore, when I download the imputed genotype data online, I found that there are two parts of the imputed genotype data (URL: https://www.synapse.org/#!Synapse:syn3157329) and (URL: https://www.synapse.org/#!Synapse:syn2426141). Could you please tell me which imputed genotype data should be selected for analysis? or both for analysis? And I also wonder what's the difference between the two imputed genotype data?

Unfortunately, those data are missing from the data contributors. We will be releasing another version (imputed to HRC) in the fall. I'm sorry for the inconvenience.
Hi, I can not find the *.fam data (syn2426141) for chop_Illumina which contains 308 individuals. We could know these individual information from the genotype data (syn7824841), but I am not sure the corresponding order in the imputed genotype file. Thanks Ting
I think you'll need to find that information from the 1000 Genomes Project website. The reference panel used is 1000 Genomes Project Consortium interim phase I haplotypes, 2010-2011 data freeze.
Thank you for your reply~ and yes the Plink can read imputation data in a variety of formats including dosage format. And I would like to ask if there is any .map data with imputed dosage format data?
The sample files are contained in the same folder. They have extension *.fam. Hope that helps.
Thank you for your reply~ and yes the Plink can read imputation data in a variety of formats including dosage format. But I want to get just ped/map format genotype data other than using plink software to analysis something. And I find the GTOOL software can convert .gen format to ped/map format. And I find that the dosage and gen genotype format are very similar. But the problem is when I want to add something to dosage file so that can be GTOOL input gen file, I can't known how to do?

The data are only provided in dosage format. My recollection is that Plink can read imputation data in a variety of formats and a number of tools are available to reformat genotype files.
Thank you for your reply~Another question is whether you have imputed data in plink format? Or could you tell me how to change these raw imputed genotype data to plink format?
@adelalady- The first files come from the Affy chip and the second files come from the Illumina chip, and contain non-overlapping samples. Solly
