12TITLE           MOVE MODE
13
14OCCURRENCE      ARB_NT and ARB_PARSIMONY: <MOVE> button in the left column
15
16DESCRIPTION     The 'MOVE MODE' allows to change the topology of the
17                displayed tree by moving subtrees.
18
19                Click on the <MOVE> button in the left column of
20                the main window.
21
22                Move subtree:
23
24                     Drag and drop a branch onto a target branch, to remove the branch
25                     from the tree and insert it next to the target branch.
26
27                Move Group Info:
28
29                     Use the right mouse button to move the group information only.
30                     When dropped onto another group, both group informations will be
31                     exchanged.
32
33SECTION         ARB_PARSIMONY specific
34
35                Within the 'ARB_PARSIMONY' window, this mode can be used to test
36                tree topologies with respect to maximum parsimony criteria by
37                moving subtrees. The current parsimony value is shown after the
38                'Current Par' prompt and can be compared with the 'Optimum Par'
39                value of the initial tree (see LINK{pa_value.hlp}).
40
41
42NOTES           If you move group info in a tree that contains LINK{keeled_groups.hlp},
43                you'll probably encounter a special error message,
44                stating that a group could not be moved because otherwise
45                groups would partly overlap, which is impossible.
46
47                A simple example would be the following tree (which has
48                invalid group definitions):
49
50                              G1 = !K1
51                             /
52                         R---
53                             \
54                              G2 = !K2
55
56
57                If all tags are groups here, the original groups for '!K1' and '!K2'
58                would be equivalent to
59
60                 * K1 = R+G2
61                 * K2 = R+G1
62
63                which is impossible (because K1 and K2 share R, but none of
64                them is completely contained in the other).
65
66EXAMPLES        None
67
68WARNINGS        It is recommended to copy the tree before using the 'MOVE MODE',
69                to avoid problems caused by that bug:
70
71BUGS            Undo 'Move Group Info' does not work (leads to loss of groupname).
