Short Description

PAINT is a Java application for viewing and annotating phylogenetic trees.

Links

http://sourceforge.net/projects/pantherdb/files/PAINT/

Requirements

  • Java

User notes

  • The program is still a bit bug-y, but the developers are more than willing to listen and make changes.

Set Up

  1. Download from sourcefouge of Panther -- http://sourceforge.net/projects/pantherdb/files/PAINT/
  2. Open terminal, go into folder & type ./launchPAINT.sh
    PAINT will do a bunch of stuff & open a GUI
  3. Go to “File” & click on “Log in” – it will do this automatically (b/c it’s a local install)
  4. Go to “File” & click on “Open from database”
  5. Pick a gene to search for – mutL & click on “Search”. Wait.
  6. Once it builds the tree, you can look at what has exptal evidence (red gene names) & what doesn’t (grey gene names).

Operating

  1. You can drag & drop annotations (i.e. DNA binding, ATP binding) to various branches of the tree when you get a green + symbol (ok by taxon constraints)
    - When you try to drag & drop an inherited annotation onto a wacky branch, i.e. something that fails taxon constraints, it will not let you drop the annotation.
    - i.e. if you try to drop a pollen process term on non-plants, it won’t even offer you the green +
    - When you drag & drop, the red gene names (with exptal evid) stay red, but the grey genes under that node now show in blue & have an annotation with the evidence code of IBA (inferred by biological ancestor).
  2. If you close the window, you will have to re-launch the program from the terminal!!!
    - I have NOT figured out how to “undo” - Suzi says "undo" is broken!
  3. At the bottom is a list of Annotations & Evidence – annotations are obviously those with exptal evidence, evidence is for you to put in text – how to think of the annotation spread, why you made that spread, why this is wrong or that is wrong. IS visible to the public – when make the GAF???
    - Similar to our notes field from CACAO (what fig, table)
  4. In the trees constructed for any gene, there are circles & squares -- circles are speciation events, squares are duplications.
    - If you right click on one of those symbols, you will be able to "collapse node" (still in tree, will get propagated annotatinos) , reroot to node (we only want to look at this node and not other stuff) , output seq ids for leaves, Prune (get rid of this entirely from the tree, does not get propagated annotations).
    - When you collapse a node, it will be a rectangle instead. If you scroll over in the "Protein Information" tab, it will tell you what species/family/etc.
  5. When you want to, go to "File" and "Save annotations". This will make a series of files, including a GAF file on your desktop. You can then use this file as something to open instead of the "Open from database".
  • what PAINT still cannot do is judge how “evolve-able” the sequences are.
  • useful form of QC b/c should paint a coherent picture – gives context for annotators
