====== Time point ======

Timepoints are objects that hold values and that are used in other objects of the model, for instance in [[Events|Events]] and [[Expression|Expression]]. 


===== Creating a Time point =====

From the [[Projects_window|Projects window]]

  * Expand the Project to which you wish to add the compartment by clicking the + symbol next to it. Right-click on ‘Blocks’, or a [[Sub-system|sub-system]] in ‘Blocks’, and select **Time point** from the pop-up menu.

From the [[Matrix_window|Matrix window]]

  * Right click an empty diagonal cell of the matrix and select **Time point** from the the pop-up menu.

From the [[Blocks_window|Blocks window]]

  * Place the mouse cursor over the table and right-click on it. Select **New | Time point** from the pop-up menu, //or//
  * In the title bar, select **Time point** from the **Type** drop-down list and click on the {{:New24.png|New}} button.

===== Editing a Timepoint =====

The block editor is shown by right-clicking the block in a window and selecting **Edit**. In the [[Blocks_window|Blocks window]], you can also show the block editor by selecting the block and clicking the {{ :Edit24.png|Edit }} button, or by double-clicking the right-most “validation” column of the block.

The block editor has three tabs:

==== Properties ====

This page lets you edit basic properties such as name, sub-system and base unit. See [[Editing_properties|editing properties]] for more information.

==== Appearance ====

This page lets you edit the visual properties of the block in the [[Matrix_window|matrix window]] and [[Graph_window|graph window]]. See [[Editing_appearance|editing appearance]] for more information.

==== Values ====

Here you edit index specific values such as nominal values. See [[Editing_values|editing values]] for more information.


**Dimension** - You can specify the dimension of the parameter by using the **Type** drop down list. Depending on the dimension the index drop down lists are activated.

**Data** - The data table contains the following columns: 

  * **Indices** - For timepoints that are non-scalar, the first columns will specify indices from the {{ :timepoint.png?100|}}[[Index_list|Index list]]s. This allows you to specify different values for different indices. The top row is named “default” and can be used when the same value should be set for all indices. 
  * **Settings** - By clicking on settings, option to change the **mode** appears. Adjacent to this, options for selection of value will change. Default mode for the Timepoint is set in **date** format. 
  * **Value** - By clicking in the value field a dropdown to select the value will appear. In case changes in mode were made, different values for timepoint can be selected as values. 


==== Database ====

The database tab lets you quickly import values for the edited timepoint from either the local or external database.

|Note|Most block properties can be edited directly in the [[Blocks_window|Blocks window]].|
