| 12 | TITLE LENGTH and MULTIFURC MODE |
|---|
| 13 | |
|---|
| 14 | OCCURRENCE ARB main window <button in the left column> |
|---|
| 15 | |
|---|
| 16 | DESCRIPTION Both modes described here allow you to increase or reduce the length of |
|---|
| 17 | terminal and internal branches. |
|---|
| 18 | |
|---|
| 19 | Click on the eleventh resp. twelfth button in the left column of |
|---|
| 20 | the ARB window to activate the 'LENGTH MODE' resp. 'MULTIFURC MODE'. |
|---|
| 21 | |
|---|
| 22 | Change branch length: |
|---|
| 23 | |
|---|
| 24 | Click and drag a branch to change its length. |
|---|
| 25 | |
|---|
| 26 | If you use the right mouse button, discrete values |
|---|
| 27 | will be used for the length. |
|---|
| 28 | |
|---|
| 29 | Set branch length to zero: |
|---|
| 30 | |
|---|
| 31 | Point to a branch with the mouse and hit the key '0' (zero). |
|---|
| 32 | |
|---|
| 33 | SECTION Differences between LENGTH- and MULTIFURC-MODES |
|---|
| 34 | |
|---|
| 35 | The LENGTH MODE simply changes the length of the targeted branch. |
|---|
| 36 | |
|---|
| 37 | The MULTIFURC-MODE changes the length of the targeted branch as well, but |
|---|
| 38 | also distributes its length-change to its direct (non-zero-length) |
|---|
| 39 | neighbour-branches. |
|---|
| 40 | Distribution is based on the same algorithm as LINK{multifurcate.hlp}. |
|---|
| 41 | |
|---|
| 42 | NOTES To multifurcate explicit single branches, you may as well focus the tree-display, |
|---|
| 43 | move the mouse pointer to the bootstrap value of the branch to eliminate and then |
|---|
| 44 | press '0' to actually eliminate the branch. |
|---|
| 45 | |
|---|
| 46 | Increasing the length of a branch in MULTIFURC-MODE may cause neighbour branches |
|---|
| 47 | to become multifurcations. This is irreversible, i.e. reducing the length back |
|---|
| 48 | to the original value will not "un-multifurcate" the affected branches. |
|---|
| 49 | |
|---|
| 50 | In both modes it is possible to set branchlengths to negative values if expert-mode |
|---|
| 51 | is enabled. |
|---|
| 52 | |
|---|
| 53 | EXAMPLE None |
|---|
| 54 | |
|---|
| 55 | WARNINGS In MULTIFURC MODE you may not expect to undo all length distributions, by |
|---|
| 56 | scaling the branchlength back to the original value it had before a previous |
|---|
| 57 | scale operation! |
|---|
| 58 | |
|---|
| 59 | BUGS unknown |
