failed to identify which build for 1000g reference build on chr17

[celisungmail]

Hello,

I tried to run SSIMP and took ALL.chr{CHRM}.phase3_shapeit2_mvncall_integrated_v5a.20130502.genotypes.vcf (hg19) as reference panel but I found the log file showed that SSIMP identified which_build=hg19 for 1000g reference build on chr17 as following. I am wondering whether there is a way to specify the build for both gwas and reference panel.
Thanks,
