Next: Aligning without additional Up: Multiple Alignment Just Previous: Multiple alignment -


In order to align sequences to an existing alignment (in this context, an existing alignment may consist of a minimum of only one sequence) the alignment must be in 'block_file' format. Essentially this is the same as the file produced by the print_vertical command and may even contain conservation information which is ignored when the file is read in. The minimum requirements for a block_file are given in appendix 2.
