Example files for v8 - model pause & input new files

[Kate Jones]

Hi all, 

Can someone point me to an example file for v8 where the model is told to pause so new files can be input?

I see that pausing is an option on pg. 4 of the v8 user guide but am having trouble finding an example. 

Thanks for your help,

Kate

Hi Kate,

Matthew Duveneck helped me with this recently. My goal was to iteratively input new ignition probability maps for prescribed fire in the SCF extension.

In your scenario file, you can add a line that will run an external R script. The first few lines of the scenario file look like this:

LandisData  Scenario
Duration  10
Species   species_LTB.txt
Ecoregions      ecoregions.txt
EcoregionsMap   ecoregions.tif
CellLength  100 << meters, 100 x 100 m = 1 hectare
ExternalCommand "Rscript pause_test_SCF.R"  

In my case, the R script uses the fine fuels raster from a given time step to generate a new map of prescribed fire ignition probabilities. To bring these in to SCF, the first few lines of my text file look like this.

LandisData  "Social Climate Fire"
Timestep                            1
Species_CSV_File Fire_Spp_Table.csv
AccidentalIgnitionsMap     Accidental_Ignition_Map.tif
LightningIgnitionsMap  Lightning_Ignition_Map.tif
RxIgnitionsMap  Lightning_Ignition_Map.tif << just a placeholder, will be overwritten immediately

DynamicRxIgnitionMaps << Optional
1  ./external_dynamic_input_maps/Rx_Ignition_Map1.tif
2  ./external_dynamic_input_maps/Rx_Ignition_Map2.tif
3  ./external_dynamic_input_maps/Rx_Ignition_Map3.tif
4  ./external_dynamic_input_maps/Rx_Ignition_Map4.tif
5  ./external_dynamic_input_maps/Rx_Ignition_Map5.tif 

Happy to share more with you if it would be helpful, though I'll be out on paternity leave the next couple weeks. My email is graham.frank at oregonstate.edu
