Genotype probabilities (from calc.genoprob
) and/or
imputations (from sim.geno
) are subset to a grid of
pseudomarkers.
This is so that, in the case of high-density markers, we can do the
genome scan calculations at a smaller set of points (on an
evenly-spaced grid, but not at the markers) to save computation time.
You need to first have run calc.genoprob
and/or
sim.geno
, and you must use stepwidth="fixed"
.
When plotting results with plot.scanone
, use
incl.markers=FALSE
, as the output of scanone
won't include information about the marker locations and so will plot
tick marks only at the first marker on each chromosome.
