====== Codon Table Library ======
The Codon Table Library is part of the [[ui:Library Explorer]], where codon tables can be stored for use in [[guide:backtranslate | backtranslation]] or sequence viewing.

==== Organization ====
  * Codon tables are organized within folders.
    * The toolbox is pre-loaded with a set of codon tables.
  * New folders can be created by selecting "add new folder / group" from the "add" button at the bottom of the Library Explorer.
  * A folder may be moved within the codon table library by selecting the icon and dragging it to a new position.

==== Adding, removing and editing codon tables ====
    * A table may be added to the toolbox by 
      * selecting "add new codon table" from the "add" button at the bottom of the Library Explorer.
      * copying an existing table in the library (not yet working in the beta version)
        * by right clicking on the icon and selecting "copy codon table"
        * by dragging the icon of the table to a new position in the library while holding down the ctrl key
    * A table may be deleted from the library by selecting it and clicking on the "delete" button at the bottom of the Library Explorer.
    * A table may be edited within the toolbox by 
      * selecting it and clicking on the "edit" button at the bottom of the [[ui:Library Explorer]].
      * double clicking on it.

==== Importing codon tables using DNA2.0's web service ====
    * A table may be imported into the toolbox by 
      * selecting "import codon table" from the "add" button at the bottom of the Library Explorer (not yet working in the beta version).
      * selecting "import codon table" from the "File" menu in the [[ui:Construct Editor]]

    * The desired table can be located by typing in part of the name of the organism into the search window
      * the search works using genus / species names
      * common names can also be useful
        * try searching for "human" to get a sense of the search process

==== Codon table format ====
    * Codon tables contain frequency data:
      * The "codon count" column is the only one that can be edited; it represents the number of times that each codon occurs within the genes of the selected organism. 
      * All of the other columns are calculated from the count data.
    * Tables can be sorted by codon or amino acid by clicking on the column header.

==== Preloaded tables are different ====
  * Preloaded tables  may be updated from time to time with new versions of GeneDesigner.  They therefore differ from user-added tables in the following ways:
== Moving pre-loaded tables ==
  * Moving a pre-loaded table will automatically create a copy of the table.
    * When tables are updated, only the tables in their original locations will be updated.

== Editing pre-loaded tables ==
  * Pre-loaded tables must be copied before editing.

== Deleting pre-loaded tables ==
  * Pre-loaded tables cannot be deleted.
