I have a large imputed GWAS dataset, however I would only like to continue my analysis with only some of the SNPs. I used Mach to impute my data and all files remain in this format. What programs can take a list of SNPs and retrieve these genotypes from my imputed data set?

See How to analyze imputed GWAS data

Also, Analysis of dosage data, read in the dosage files and try --extract?

Thanks for your thoughts. yes, I've seen that previous post but it wasn't helpful :( . I need to filter for specific SNPs in the imputed file (done by Mach) and run my GWAS on those. Do you know if --extract works with dosage files in Plink?

I tried this and the --extract command doesn't work. Any other thoughts?

Could you find the solution? I have imputaed SNPs file in Minimac3 and I'd like to extract a especial set of imputed SNPs. Which software or method you used?

Thank you.
