There is a tool to convert from structure file to VCF file format?
Or there is another format to use in Beagle 5?
What is "structure format"?
You can use the software PGDspider to convert between format, I know it works from VCF to structure so it should work the other way.
It didn't work for me.
Do you know a way to use plink to make the conversion?
what error message do you get when you try to do the conversion?
