What is Mussagl?
----------------
+Mussa is an N-way version of the FamilyRelations (which is a part of
+the Cartwheel project) 2-way comparative sequence analysis
+software. Given DNA sequence from N species, Mussa uses all possible
+pairwise comparions to derive an N-wise comparison. For example, given
+sequences 1,2,3, and 4, Mussa makes 6 2-way comparisons: 1vs2, 1vs3,
+1vs4, 2vs3, 2vs4, and 3vs4. It then compares all the links between
+these comparisons, saving those that satisfy a transitivity
+requirement. The saved paths are then displayed in an interactive
+viewer.
Short History of Mussa
----------------------
Mussa Python/PMW Prototype
~~~~~~~~~~~~~~~~~~~~~~~~~~
+First Python/PMW based protoype.
Mussa C++/FLTK
~~~~~~~~~~~~~~
+A rewrite for speed purposes using C++ and FLTK GUI toolkit.
Mussagl C++/Qt/OpenGL
~~~~~~~~~~~~~~~~~~~~~
+Refactored version using the more elegant Qt GUI framework and
+OpenGL for hardware acceleration for those who have beter graphics
+cards.
Getting Mussagl
===============
(We only want to annotate CDS and UTRs.)
2. Select **one fasta record** per **region**.
(Mussa needs each CDS and UTR represented by one fasta record per CDS/UTR).
- 3. Select **split UTR and CDS parts of an exon into separate FASTA records**.
- (Breaks up **exons** into CDSs and UTRs.)
+ 3. Select **CDS in upper case, UTR in lower case.**

+Sub-analysis
+------------
+To run a sub-analysis **highlight** a section of sequence and *right
+click* on it and select **Add to subanalysis**. To the same for the
+sequences shown in orange in the screenshot below. Note that you **are
+NOT limited** to selecting more than one subsequence from the same
+sequence.

+
+Once you have added your sequences for subanalysis, choose a `window size`_ and `threshold`_ and click **Ok**.
+
+.. image:: images/subanalysis_dialog.png

+
+A new Mussa window will appear with the subanalysis of your sequences
+once it's done running. This may take a while if you selected large
+chunks of sequence with a loose threshold.

+Copying sequence to clipboard
+-----------------------------
+
+To copy a sequence to the clipboard, highlight a section of sequence,
+as shown in the screen shot below, and do one of the following:
+
+ * Select **Copy as Fasta** from the **Edit** menu.
+ * **Right Click (Left click + Apple/Command Key on Mac)** on the highlighted sequence and select **Copy as Fasta**.
+ * Press **Ctrl + C (on PC)** or **Apple/Command Key + C (on Mac)** on the keyboard.
