===== Documentation of the assessment =====

This part of the screen allows you to describe your assessment and to attach relevant documents.

  * **Author** - You can enter your name here, as the author of the assessment.
  * **Description** - To change the description, click on the **Edit** button.
  * **Documents** - Click on the **Add file…** button to attach a document to your assessment. This could be an image, or a PDF file. You can double-click a document in the list to view it in an external program.

Note that file should be presented at the same PC where Ecolego player is used. 
===== Contaminants =====

The two lists show all contaminants/materials that are available. By clicking contaminants in either list, you can select or deselect contaminants to be included in the assessment. Contaminants which are deselected are disactivated instead of being removed from the assessment. This means that if you enter input data for a specific contaminant, but want to run a simulation without it, you can safely deselect it without loss of information.

Lists are empty before excisting model is opened.

**Filter** is used for navigation trought contaminants.  


===== Indices =====

This option will only be available for models where secondary listings of dependencies have been defined. Such a listing could be, for instance, biota, target age groups or food types. Each secondary listing will be listed behind tabs. You select the tab for a specific listing, and a similar listing as for contaminants will appear.

==== Adding new indices ====

To add a new index, you must first select which listing of indices to modify by clicking it’s corresponding tab. After, click the {{:New16.png}}**Add Index** button in the menu and enter a name for the new index.
