Desde já podemos comparar os grupos formados com o mapa já publicado, para sabermos a correspondência entre ambos. Para facilitar, fizemos esta tabela com os nomes dos marcadores que compoem o mapa publicado, sendo que cada coluna da tabela corresponde à um grupo de ligação.
ref <- read.csv(file = "LG.csv", stringsAsFactors = FALSE)
names <- colnames(data1$geno)[LGs.HMM.force[[2]]$seq.num]
comp <- pos <- lgs <- pos2 <- num_lgs <- list()
for (i in 1:length(ref)){
comp[[i]] <- ref[[i]] %in% names
pos[[i]] <- which(comp[[i]] == TRUE)
lgs[[i]] <- ref[[i]][pos[[i]]]
pos2[[i]] <- names %in% lgs[[i]]
num_lgs[[i]] <- LGs.HMM.force[[2]]$seq.num[pos2[[i]]]
}

Com as informações da tabela sabemos que o grupo 2 formado tem marcadores que estavam presentes no grupo 2 do mapa publicado.

Aqui aderimos a ordem dada pela opção “safe” e removemos também o marcador 45 conforme observação do heatmap.

Ao serem inseridos no mapa, esses marcadores aumentavam o tamanho, diminuiam a verossimilhança e fugiam do padrão esperado no heatmap
