mfmapd

Computes an intuitively nice marker ordering using 2-points distances.

Synopsis:

The mfmapd command is invoked as either one of :

Description:

The mfmapd command builds gradually a map by inserting the best (whose distances are minima) available pairs of markers among the current list of active markers. This ``Greedy'' heuristic applies a multi-fragment (mf) strategy: several order fragments of markers which are close together are constructed and then linked together.

Warning: since 2-points estimations are typically unavailable for some pairs of markers when data-sets are merged, this command will return very poor maps on such merged data. This command should especially not be used when two data-sets have been merged with separate parameters estimation (using mergor).

Arguments:

Returns:

nothing.

Example:

CG> dsload Data/bc.cg

CG> mfmapd

Map -1 : log10-likelihood =  -321.28

   1 : MS1 MS2 MS3 MS4 MS5 MS7 MS6 MS8 MS11 MS10 MS9 MS14 MS12 MS13 MS16 MS15\
 MS17 MS18 MS19 MS20
