Hi,
Can someone help me understand the values in these files? There are many 2s, 1.5XXXX; what does that mean, and what is the reference genome for this data? I couldn't find a very useful reference. Thanks a lot!

Thanks will. This is very helpful! hello @XiaoqingHuang,
Sorry for the slow response. I found a previous discussion that I believe should answer your question, but let me know if it does not:

As for the reference genome, it looks like the SNP array can be mapped to GRCh38 coordinates: https://docs.gdc.cancer.gov/Encyclopedia/pages/Affymetrix_SNP_6.0/
Best,
Will @Mette Thanks!
