Key Error when trying to run data.process_gwas_file()

[pensive-bubble]

Hello,
I'm trying to run using my own GWAS summary statistics. My input file is below

When I reach data.process_gwas_file(), I get KeyError: 'rs62513865'. Do you know why this might be?

I have also tried to use another input file with just CHR, SNP, P, and N, but run into KeyError: 'BETA' when i run data.process_gwas_file(). Your documentation says I only require these 4 columns. Do you know what the issue is for this?

Finally, I don't seem to have an alternate allele frequency in my summary stats (https://pgc.unc.edu/for-researchers/download-results/ - I'm looking at the latest ED results). Will this be a problem?
