# Add Sequences to Blocks

Add sequences to blocks aligns a set of Blocks with one or more protein sequences, saving the best score only for each alignment. It adds each protein sequence to the blocks if the best alignments are in the correct order and non-overlapping, re-weights and re-calibrates each block.
You can make blocks from unaligned protein sequences with Block Maker.
If you need to convert another multiple alignment to BLOCKS format, use the Multiple Alignment Processor or the Block Formatter.
