1. Import the branch locations into PCRaster. This is done with the PCRaster general adaptor export, which produces branch0000.000 file.
   • Copy the X and Y locations from the Branches.xml and make an new irregular grid (XXX_branch_grid) in Grids.xml
   • Make a new location ID for XXX_branch_grid.
   • Make XXX_interpolate_grid_to_branch_grid file. This file converts the locationid from XXX_merged to the XXX_branch_grid. And back to the XXX_merged grid, making use of inverse distance interpolation technique. Adapt the search radius to grid size. (= smaller than half a grid cell)
   • Make general adaptor run file: XXX_PCR_generate_branch_file. This file exports the branch0000.000 file.
2. Make stream flow direction map.
   • Export the stream flow direction map with the Modflow general adaptor
   • Rename stream flow direction asci file into "strdir.asc"
3. Make initial scalar and ldd map
   • use mapattr command to produce scalar.map -> mapattr scalar.map
     number of columns =360
     number of rows=240
     data type = scalar
     projection= y increases from bottom to top
     x upperleft corner=400000
     y upperleft corner=170000
     celllength = 250
   • use mapattr command to produce ldd.map -> mapattr ldd.map
     number of colums =360
     number of rows=240
     data type = ldd
     projection= y increases from bottom to top
     x upperleft corner=400000
     y upperleft corner=170000
     celllength = 250
4. Make a new temporary workflow (e.g. XXX_configuration_only) and adapt the WorkflowDescriptorDescriptors and the ModuleinstanceDescriptors file
5. Run workflow XXX_PCR_generate_branch_file. This run produces the following files: brances_grid.map, cross_points.map and stream_directions.map
6. make XXX_QTRIB_ref(Historic) transformation file (as described in step 7 using the moduleinstance generation spreadsheet)
7. adapt interpolation and compare files (as described in step 7 using the moduleinstance generation spreadsheet)
8. adapt Moduledescriptor and ModuleinstanceDescriptors if still applicable

The instructions are also explained in the attached word document, which also includes some examples of resulting files.
