Imputation and visualisation in Marmal-aid. (A) The left panel shows the percentage of probes that were imputed to within 0.2 of the actual beta value for over 100 different random samples. On average over 96% of the probes were imputed to within 0.2 of the actual value. The right panel shows an example of 1 of the 100 random samples in which the actual beta value is plotted on the x-axis and the imputed value on the y-axis. (B) An example of the GUI available at http://marmal-aid.org/visualise.html for chr1:67,217,505-67,219,505 around the TSS of TCTEX101.
