Hello, I am planning to use the harmonized WGS ([syn22264775](syn22264775)) and hamonized RNAseq ([syn21241740](syn21241740)) data in my analysis. The description of the harmonized RNAseq states that _"RNAseq data in this study has been aligned to the GRCh38 reference genome"_. For the harmonized WGS, the description says that _"Previously available BAM files from these samples aligned to the GRCh37 genome build have been archived"_. However, I am not sure if this means that the harmonized WGS VCF files were aligned to GRCh38 or still aligned to GRCh37. The information about the WGS for each individual cohort (MSBB, Mayo, ROSMAP) state that they were aligned to GRCh37, but I am unclear about the harmonized data. It would be really helpful if someone can help me with this. Thanks!
