Show-tiling attempts to construct a tiling path out of the query contigs as mapped to the reference sequences. Given the delta alignment information of a few long reference sequences and many small query contigs, show-tiling will determine the best mapped location of each query contig. Note that each contig may only be tiled once, so repetitive regions may cause this program some difficulty. This program is useful for aiding in the scaffolding and closure of an unfinished set of contigs, if a suitable, high similarity reference genome is available. Or, if using PROmer, show-tiling will help in the identification of syntenic regions and their contig*s mapping to the references.

MUMmer or 'Maximal Unique Matches' is a bioinformatics software system for sequence alignment. It is based on the suffix tree data structure and is one of the fastest and most efficient systems available for this task, enabling it to be applied to very long sequences. It has been widely used for comparing different genomes to one another. In recent years it has become a popular algorithm for comparing genome assemblies to one another, which allows scientists to determine how a genome has changed after adding more DNA sequence or after running a different genome assembly program.
