Question about allele frequency when formatting sum stats with munge_sumstats.py

[NRRdy]

Hello,

One of my GWAS sum stat files provides a frequency column for the alt allele, and the other provides the allele frequency for allele 1 (which I assume is the reference allele - I'm going to attempt to confirm that). Can I just provide both of these frequency to columns to munge_sumstats.py like I did below? Or do I need to convert the frequency column in one of the summary stats files so that is consistent with the other?

Thank you!
