Quick parameter import

This window allows you to quickly import values to a specific parameter from either the local or external database. If you follow the same naming conventions in your model and database, this window can also help a lot in finding relevant parameter values by using the “auto-match” feature.

The procedure is simple: search the database using specific criteria, then assign values to the parameter by selecting indices from the “match” column of the result table.

The window is divided into four sections: Search, Match, Filter and a table.

This window lets you give criteria for a database search.

  • Name - Enter the name of the parameter here. If you are unsure of the exact name you can use an asterix (’’) as a wildcard, or leave the field empty.
  • Max hits - The maximum number of search hits to present in the table. This limit is necessary when searching a very large database, or when using wildcards in the search name.
  • Search - Click this button to start the search.
  • Stop - Click to stop an ongoing search.
  • Clear - Clear the search result table
  • Database - Select either the local or external database. Refer to Setting up an external database for instructions on how to set up and connect to an external database.

Search result table

If you let the mouse cursor hover over a parameter in the table, a tool tip will be present the data of the parameter. In the bottom right area under the table, the number of result hits are presented and how many parameter values have been matched.

  • Match - This is where you assign values to your parameter. When you click in this cell, a menu let you choose from all available indices for the parameter. Naturally, an index can only be matched with one search result.
  • Name - The name of the parameter as given in the database.
  • Value - The nominal (deterministic) value of the parameter.
  • Distribution - The probability density function of the parameter.
  • Unit - The parameter unit.
  • Usability level - This field only applies when searching the external database, and is a rank for the usability of the parameter.
  • Insert date - The date the parameter was added to the database.

The following columns are hidden by default, but can be displayed by clicking the button:

  • Full name - The full name of the parameter.
  • Dependencies - The type of dependence, for instance “Element” or “Nuclide”.
  • Confidence - The confidence in the parameter value.
  • Usability - A description of the Usability Level.
  • User - The user who entered the parameter value into the database.
  • Comments - Comments for the parameter.
  • Reference - A reference for the parameter, for instance to litterature or a report.
  • Type - The type of parameter

Match & Assign

Often it is valuable to let Ecolego guess on which values to match. For this Ecolego uses a list of prioritized properties.

In an iterative procedure, Ecolego examine one index at the time and rank all the search results to that index. By default, the name of the parameter is the highest ranked property. That is, the name of the parameter (as defined in your model) compared to the name given in the database. If several parameters in the database have the same name as your parameter, the indices of the parameter values are looked to. If several entries exist that also match the current index, the usability level is examined, and so forth.

  • Assign - Assign the selected matched values to the parameter.
  • Overwrite - When assigning values, overwrite existing non-empty values.
  • Auto-match - Let Ecolego match all parameter values for you using the method described above.
  • Prioritize - Change the rank given to each property.

Filter

  • Hide irrelevant indices - Hide all results for parameters that have indices that do not apply to the target parameter.
  • Hide un-matched rows - Lets you quickly display only the rows that have been matched.
