Dear all,

 

I am running qtl mapping. I have 75 RI lines with some residual
heterogeneous loci. The loci are code A, B or H(heterogeneous).

Questions:

1) R/qtl determine the data is F2 intercross.

2) Warning message about strange genotype pattern

 

> library(qtl)

> dat=read.cross("csv", file="rqtl_trt.csv")

 --Read the following data:

         75  individuals

         80  markers

         1  phenotypes

> summary(dat)

    F2 intercross

 

    No. individuals:  75 

 

    No. phenotypes:   1 

    Percent phenotyped:  100 

 

    No. chromosomes:  4 

    Total markers:    80 

    No. markers:      17 20 3 40 

    Percent genotyped:  100 

    Genotypes (%):      AA:41.3  AB:4.7  BB:54  not BB:0  not AA:0 

 

Thank you for your help

 

Lang
