mrkmerge

Merges two markers in one.

Synopsis :

The mrkmerge command is invoked either as:

• mrkmerge Options
• mrkmerge mrkid1 mrkid2

Description :

The command is used to merge two markers whose observed genotypes on all individuals are compatible with each other (closely related markers for which no recombination has been observed). Such ``double markers'' are identified automatically using the command mrklod2p.

Arguments :

• Options : -u to obtain the synopsys of the normal use, -h to print a one line description, -H to print a short help.
• mrkid1 mrkid2: the observations on marker number mrkid1 and marker mrkid2 are merged in the marker mrkid1 and the marker mrkid2 is removed from the set of selected markers.

Returns :

Nothing

Example :

# we first load a data set
CG> dsload Data/bc.cg
{1 f2 backcross 20 208 /homes/thomas/carthagene/test/Data/bc.cg}
# and ask for markers that can be merged
CG> mrkdouble

Possible double markers:

                MS9 = MS10            [7.2]
                MS9 = MS14            [3.6]
               MS10 = MS11            [3.6]
               MS11 = MS14            [3.6]
               MS12 = MS13            [18.7]
               MS12 = MS14            [3.6]
               MS13 = MS14            [6.0]
               MS14 = MS16            [3.6]
               MS14 = MS17            [1.5]
               MS17 = MS18            [16.0]


# then merge markers 9 and 10 in 9.
CG> mrkmerge [mrkid MS9] [mrkid MS10]
Markers 9 and 10 merged in 9.
