Hi, I have some problem with the AMP-AD_ROSMAP_WGS data. I cannot link each row (ie each 'mutation) in vcf files to specific samples (for example, https://www.synapse.org/#!Synapse:syn10997292). In that , I have no idea whether the sample is patient or control, from blood or brain genomic DNA. There was a file named rosmap_WGS_id_key.csv. However, none of the WGS_id and projid are contained in the vcf files. In this way, I cannot locate each mutation to specific sample ID. Could you please show me a way to resolve this question? I saw threads about this problem a couple of years ago in the forum. I guess it may have already been solved. Thank you very much for your kindly help! Best wishes, Fan
