mfmapl

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

Synopsis:

The mfmapl command is invoked as either one of :

• mfmapl Options
• mfmapl

Description:

The mfmapl command builds gradually a map by inserting the best (whose LOD criteria 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:

• Options : -u to obtain the synopsys of the normal use, -h to print a one line description, -H to print a short help.

Returns:

nothing.
