    2 The first task in building an Ecopath model is to define the models functional groups (called Groups or Boxes). Groups are species or collections of species that share similar population dynamics and ecological function. See [wiki:EwEugDefiningTheSystem Defining the system] for more on how to define groups.

    44To add and edit functional groups to an Ecopath model, choose the ''Edit groups...'' option on the [wiki:EwEugEcopathMenu Ecopath menu] on the ''Menu bar''. This will open a form where you can add, delete, name and sort the functional groups in your model. 
     
    1010'''Add/insert groups''' 
    1111 
    12 Add groups using the'' Insert'' button. In a brand new model, groups will be inserted above the detritus group. In an existing model, select the row where you would like a new group inserted and click ''Insert''. A new group will be added above the selected row. If no row is selected, new groups will be added above the first row. Note that when you add a new group, its status in the ''Status'' column will be given as “To create”. Clicking the ''OK'' button closes the ''Edit groups'' form and implements the group insertion.

    1515 
    16 New groups are given the default name “New Group”. Edit group names by clicking once in the appropriate'' Group name'' cell. The box will be highlighted and you can start typing. To edit an existing group name, click on the name and the name will be highlighted. You can then edit the name.

    1717 
    1818__Important note__: Group names should be unique. If you have multi-stanza groups  in your model (see section below), each stanza should have a unique group name (e.g., Small juvenile cod; Large juvenile cod; Adult cod). The name of the multi-stanza group as a whole (e.g., Cod) is entered under ''Multi-stanza group name''. See section on multi-stanza groups below for more detail on defining multi-stanza groups. 
     
    3434'''Delete groups''' 
    3535 
    36 Groups can be deleted from the model using the ''Delete ''button. Models selected for deletion will be marked “To delete” in the ''Status'' column. Clicking the ''OK'' button closes the ''Edit groups'' form and implements the group deletion.

    4242'''Defining multi-stanza groups''' 
    4343 
    44 The ''Edit groups'' form allows you to create groups representing life history stages or stanzas for species that have complex trophic ontogeny (see introductory material on [wiki:EwEugRepresentationOfMultiStanza multi-stanza groups] (Chapter 2 of the EwE6 User Guide) for more information on how these groups are modelled in Ecopath, Ecosim and Ecospace).

    4646'''To define a multi-stanza group:''' 
     
    5050Name the multi-stanza group as a whole (e.g., Cod) in the ''Multi-stanza group name ''column. Once you have created a multi-stanza group name, it is added to a pull-down menu in the ''Multi-stanza group name'' column. 
    5151 
    52 Enter the __start__-age of each stanza in months in the ''Stanza age (in months)'' column. Note that your youngest stanza must have a start-age of zero months. If you do not have an age-zero stanza, Ecopath will set the youngest stanzas start age to zero (a message box will inform you of this).

If you do not have an age-zero stanza, Ecopath will set the youngest stanza's start age to zero (a message box will inform you of this).

    5454IMPORTANT. After defining a multi-stanza group(s), you must set the values of additional parameters for the group(s). See [[Edit multi stanza groups.htm|Edit multi-stanza groups]] for details.
