The following table describes ways to modify an initial multiple alignment:
|Task||See this topic|
|To realign a range of aligned sequences using different parameters or a different alignment engine||Subalign sequences|
|To merge two existing completed alignments together||Merge two existing alignments (“Profile alignment”)|
|To add all/selected sequences from the “Unaligned Sequences” area into the current alignment, while retaining all of the gaps of the original, pre-merge alignment||Merge unaligned sequences into an existing alignment|
|To realign existing aligned sequences PLUS selected unaligned sequences||Align selected unaligned sequences with an existing alignment|
The following video illustrates some of these modification procedures:
