Hi all,

any advice on where i can find the genetic map for the GRCh38 version of 1000Genomes? this is needed as a parameter in the imputation process by IMPUTE2.

impute2 is extremely outdated now, its nearly 10 years and and 3 versions have been released since then. Unless there is a very good reason, you should be using impute5 https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1009049

thanks for the recommendation. the reason behind using IMPUTE2 is the -merge_ref_panels option which is not available in IMPUTE5

why not just merge them using e.g. bcftools before and then run IMPUTE5?

the idea behind the -merge_ref_panels from IMPUTE5 is that it merges one reference panel into the other then use the output for imputation. i am interested to see is one reference panel would be unable to impute the rare variants and hence the impact on the imputation process
