WitrynaRobust, highly accurate imputation results were reliably obtained with LB-Impute, even at extremely low (<1×) average per-marker coverage. This finding will have implications for the design of genotype imputation algorithms in the future. Witryna2 lut 2024 · A 2-step imputation contains the following 2 steps: (step 1) a representative subset of >= 200 unrelated individuals are used to calibrate model parameters; and (step 2) actual genotype imputation is performed for every person using parameters inferred in step 1.
