Sorting Sequences
Any group of selected sequences may be reordered by pressing the up or down arrow keys. The whole alignment may also be reordered by the use of the functions in the Sort menu (Calculate→Sort):
Sort by ID
Orders the sequences by the alphanumeric (0-9A-Za-z) precedence of their names.
Sort by Group
Places sequences in the same group adjacent to each other.
Sort by Pairwise Identity
Sorts sequences in the selection or alignment according to percent identity with respect to the first sequence in the view.
Sort by Tree Order
The leaf ordering of a particular phylogenetic tree is used to
order the sequences corresponding to those leaves in the
alignment.
If a tree has been calculated from or
associated with the current alignment, its name will appear in
the submenu Sort→By Tree Order.
Sort by alignment ordering
Multiple alignment methods often order the sequences in their
alignments by some measure of sequence identity.
If the
current alignment has been generated by one of Jalview's
alignment web services, the alignment ordering can be recovered
by its corresponding entry in the Sort menu.
Sort by Score
This menu appears if the alignment contains any sequence associated alignment annotation with associated score values. Each entry is the label for a distinct group of sequence associated annotation scores which can be used for sorting.
Sorting according to sequence features
Additional sort operations for alignments containing sequence
features are provided in the Feature
Settings dialog, opened via View→Feature

Reversing the Order
Selecting any item from the Sort menu will sort sequences in an ascending order according to the property defining the sort. If the same sort is re-applied, the sequences will be sorted in the inverse order. In both cases, for sequences which are equivalent under the sort operation, their order will be preserved (since version 2.10). In the case of trees and alignment orderings, Jalview will remember your last choice for sorting the alignment and only apply the inverse ordering if you select the same tree or alignment ordering item again.
