Editing alignments

The Alignment editor works much like a word processor.  The caret (the blinking vertical line) indicates the insertion point in the sequence.

To insert or delete characters in an alignment:

  • Position the caret at the desired insertion point.  The caret is positioned by clicking the mouse on the insertion, or by using the keyboard's arrow keys.
  • Type the desired characters on the keyboard.

To insert or delete blocks of characters:

  • Use the mouse to select (highlight) characters in one or more sequences.
  • Use the keyboard to delete the selected block of characters, or to insert a new character. Note: the new character typed will replace any selected characters.

Dragging sequences:
When the drag mode button in the tool bar is pressed, gaps can be inserted or removed in a sequence by clicking the mouse on the sequence and dragging the sequence by moving the mouse with the left button held down.

Sequence protection:
To prevent accidental alteration of the alignment, sequences can be protected, or locked.  Locked sequences have a closed red padlock symbol next to the sequence name.  Unlocked sequences have a open green padlock symbol.  To lock or unlock a sequence:

  • Select the Sequence menu
  • Select the Protections menu item
    • Select Allow all edits to enable editing on all sequences
    • Select No edits to disable editing on all sequences
    • Select Allow individual protections to set protections on individual sequences.  When this menu item is selected, clicking on the padlock icon next to the sequence name toggles protection.

Note:
Only sequence characters are permitted.  Other characters will be ignored.
