lkhocb

Computes an intuitively nice marker ordering using 2-points Obligate Chromosome Breaks criterion.

Synopsis:

The lkhocb command is invoked as either one of :

Description:

The lkhocb command converts the current marker selection and associated genetic / Radiated Hybrid data into a Traveling Salesman Problem which is solved using Keld Helsgaun's LKH software. LKH is based on the Lin-Kernighan heuristic. It is possible to collect every tour found by LKH into the CarthaGene heap, in order to get a map with a possible better multipoint loglikelihood.

Arguments:

Returns:

nothing.

Example:

CG> dsload Data/rh.cg
{1 haploid RH 53 118 /home/tschiex/Dev/carthagene/doc/user/exemple/Data/rh.cg}
CG> lkhocb 1 -1
[-822.75]
Best map with log10-likelihood = -822.75
TSP: optimum= 611.000000 lowerbound= 610.872000 gap= 0.020954% totaltime= 0.09

Map -1 : log10-likelihood =  -822.75
