Abstract Background Automated software tools for multiple alignment often fail to produce biologically meaningful results. In such situations expert knowledge can help to improve the quality of alignments. Results Herein we describe a semi-automatic version of the alignment program DIALIGN that can take pre-defined constraints into account. It is possible for the user to specify parts of the sequences that are assumed to be homologous and should therefore be aligned to each other. Our software program can use these sites as anchor points by creating a multiple alignment respecting these constraints. This way our alignment method can produce alignments that are biologically more meaningful than alignments produced by fully automated procedures. As a demonstration
