nicemapd

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

Synopsis:

The nicemapd command is invoked as either one of :

Description:

The nicemapd command orders the current list of active markers using a simple Nearest Neighbor heuristics. Starting from each marker successively, it builds a map by always selecting the nearest marker. The best map according to multipoint maximum likelihood is inserted in the heap.

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.
