To create a zone matrix from a main zone matrix, distribute the data of each main zone to its zones, and save this data to an existing zone matrix. You can distribute the data evenly or use weighting factors (Fundamentals: Converting zone and main zone matrix into each other).
1. On the toolbar, click the 
Open 'Procedure sequence' window button.
The Procedure sequence window opens.
2. To the procedure sequence, at the position of your choice, add the Matrix disaggregation procedure of the Matrices category (Setting up and starting the procedure sequence).
3. In the row of the added procedure, click the button in the Reference object(s) column.
The Select matrix window opens.
4. From the list, choose the zone matrix you want to save the disaggregated values to. Here, two methods are provided (Selecting matrices).
| Element | Description |

Select matrix directly |
From the list of all matrices, select the desired matrix by its number. |
|
Select matrix by properties |
Select a matrix by certain attributes and their values. |
5. Confirm with OK.
The selected matrix is listed in the Reference object(s) column.
6. Make sure the added procedure is highlighted. Then, in the Operations section, click the Edit button.
The Disaggregate matrix window opens.
7. Make the desired changes.

Select matrix |
Click this button to select the main zone matrix you want to disaggregate. Here, two methods are provided (see step 4). |
|
Disaggregation weights |
Two origin-destination properties that are used as weighting factors for disaggregation. You can for instance choose a matrix or an origin or destination attribute. Notes Enter 1.0 for both weighting factors to obtain an even distribution of the data among the zones. If the denominator in the formula becomes null, the data is also evenly distributed. |
8. Confirm with OK.
9. Execute the procedure (Executing procedures in the procedure sequence).
The values of the main zone matrix are broken down and the result is saved to the zone matrix selected.
