Mx matrices are best viewed using Firefox. Get Firefox here.
[edit] Introduction
[Matrices] in mx display the intersection of a series of characters and OTUs set to public by the matrix owner.
[edit] Overview of functionality
Shows the matirx, one click view for matrix cells, nexus and tnt file export, link to views for tags, characters and OTUs.
[edit] Definitions
- OTUs (Operational Taxonomic Units) are the taxa being compared.
[edit]
1. Number of OTUs and Characters in the matrix.
2. Click on a matrix cell and the OTU, Character and State information will display above the matrix.
3. Links to other display pages including:
- characters - a list of characters in the key which link to detailed descriptions of character/character states. Includes images and figures.
- grid tags - Mx [tags] are combination of a user defined keyword and an "object" (anything with a primary_id, such as an OTU, character, character state, coding, image, collecting event, specimen etc.) in mx. Within a tag an optional linkage to a reference and a custom notes/value field are also available. Tags are great way to group objects within mx, or communicate notes etc.
- trees - Link to [trees] associated with this public matrix. Mx can store phylogenetic trees. Both Newick formatted strings (a simple text field) and a fully parsed set of nodes are stored in the database. While there is currently minimal functionality for using the parent/child data the system provides a good starting point for those wishing to develop query based methods on trees.
4. Matrices are exported in nexus and tnt formats.
- save as file - downloads directly to your computer. The other print to the screen. Cut and paste the text and save as a file.
5. Change the size of a matrix display to accommodate any size screen. This functionality is particularly important with larger matrices.
6. Links to the home page and help topics for a page.
7. Click on an OTU in a matrix takes you to a OTU show page.
8. Click on a character takes you to a character show page.
