OMX file |
Enter the path for the OMX file to be imported. The path can be absolute or relative. Relative paths are interpreted by Visum relative to the project directory for matrices. |
|
Matrix reference type |
Specify the reference object for the matrices to be imported. You can select zone, main zone, and stop area. |
|
Allocation of matrix entries |
Specify how the entries in the OMX matrix are allocated to the Visum objects. OMX lookup table Select a lookup table of values to be used for allocating the rows and columns of the matrices to the selected Visummatrix reference type. The lookup tables are loaded from the selected OMX file. They must contain unique values. Visum attribute Select a unique Visum attribute for allocating the values from the lookup table. |
| Conflict handling |
Select whether new Visum matrices should be created during the import or existing matrices should be overwritten. Overwrite existing matrices If this option is selected, existing Visum matrices with identical matrix references are replaced by the imported matrices. Regenerate all matrices If this option is selected, a new Visum matrix is created for each matrix in the OMX file and all allocated matrix attributes are set at the Visum matrix. |
| Matrix selection |
Select the desired OMX matrices to be imported here. |
