Hi, everyone! First, ASA from _ILLUMINA_ means Asian Screening Array. I couldn't find this product on _ILLUMINA_ websit. However ASA seems to be Asian version of GSA, GSA:

GSA is a next-generation genotyping array for population-scale genetics, variant screening, pharmacogenomics studies, and precision medicine research.

I got a ASA result demo and want to match those SNP result to dbSNP. Result contains:

20180423_2s_ASA_v1_FinalReport_3rdparty.txt
20180423_2s_ASA_v1_FinalReport_forward.csv
20180423_2s_ASA_v1_FinalReport_standard.txt

3rdparty.txt is SNP report using Top/Bot system design by _ILLUMINA_
forward.csv is SNP report using Forward/Reverse strand system design by dbSNP
standard.txt is SNP report with all details
It seems I can grab SNP from forward.csv then search on dbSNP. (I think this file name means all result is forward strand, right?). Here is the result file format:

• header >[Header]
  GSGT Version,2.0.3
  Processing Date,4/23/2018 4:07 PM
  Content,,ASA-24v1-0-Consort_20022506_A2.bpm
  Num SNPs,698500
  Total SNPs,698500
  Num Samples,2
  Total Samples,2
  [Data]
  ,S1,S2

question: which reference was applied? GRCh38 or hg19?
here is lines in file:

• some lines are like:

• and more...

This means all those SNP are not named by the same way, maybe from different source. So how could I match those SNP to dbSNP? Any help would be appreciate, thanks!
