Prune allows one to eliminate markers or traits. It removes the data from
the file containing the cross and reconstructs the molecular map.
It requires a molecular map that could be a random one produced by
Rmap, or a real one in the same format as the output of
Rmap. The sample could be a randomly generated one from
Rcross or a real one in the same format as the output of
Prune also does bootstraps, permutations and simulations of missing or dominant markers.
