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.
