+By default your analysis is NOT saved. If you try to close an analysis

Annotation
~~~~~~~~~~
Annotations can be included on any of the sequences using the `Load a
-mussa parameter file`_ method of loading your sequences. You can
-define annotations by location or using an exact sub-sequence and you
-may also choose any color for display of the annotation; see the
-`Annotation File Format`_ section for details.

-Note: Currently there is no way to add annotations using the GUI (only
-via the .mupa file). We plan to add this feature in the future, but it
-likely will not make it into the first release.

The only real difference between an annotation and motif in Mussagl is
-that you can define motifs from within the GUI. See the `Motifs`_

You can dynamically change the threshold for how strong a match you
-consider the conservation to be with one of two options:
+consider the conservation to be by changing the value in the dynamic
+threshold box.
- 1. Number of base pair matches out of window size.
-
- 2. Percent base pair conservation.
+The value you enter is the minimum number of base pairs that have to
+be matched in order to be considered conserved. The second number that
+you can't change is the `window size`_ you used when creating the
+experiment. The last number is the percent match.
See the Threshold_ section for more information.

+experiment** after making this change by selecting **File > Save
