Hi Olivier,

Is there easy way to estimate required memory for shapeit4 in the usage?

Thanks

Hi,

Sorry, this is real hard to estimate memory usage before trying to run it as it depends on multiple factors: #samples and #variants obviously, but also heterozygosity, minor allele frequencies and missing data rate. The best way to go I guess is to run a small region as you can linearly extrapolate from there for the full dataset.

Best,

Olivier.
