Allows to split an alignment into multiple alignments.
One usecase of this function is to
split an alignment into multiple partial alignments (parts)
operate on single parts only (e.g. using an aligner)
join the (modified) parts into the original alignment using ´Concatenation of sequences´.
Insert the "Target alignment prefix". This string will be appended by digits and then gets used as names of the generated partial alignments.
Insert a list of positions (comma-separated). The source alignment will be split before each of the given positions and the splitted sequence parts will be written into separate target alignments.
The easiest way to select positions to split is to
highlight a block in the arb sequence editor and
then click "Use editor range".
Choose whether all or only marked sequences should get splitted.
You may choose to overwrite existing alignments. This will completely delete these alignments and the stored data for any species or SAI w/o further confirmation.
