After you have set up a run, simply click the “Save run” button and name the run. Two files are created in the C-ROADS-CP/Models folder, a data file, “my run.vdf”, and a settings file, “my run.cin”. The data file contains all of the data output of the simulation and the settings file contains all of the settings to replicate the run when you wish. Settings files are much smaller (~5 KB) than data files (~5 MB).

Once I save some settings, how can I retrieve them?

From the C-ROADS “CP” main screen, click the “Load stored settings” button. Select the settings file you want by clicking on its name then click “Open”. The simulation opens with those settings active.

Can I build upon a previous run that I saved? How?

Yes, two ways. From the C-ROADS “CP” main screen, select either “Load stored settings” (described above) or “Update run”. When you click on “Update run” you must select the previous run upon which you wish to build and click on “Open”. Continue to build upon your previous work.

I made an Excel file of simulator output. Where was the file saved?

The default location for files created when you select the “Export dataset” button is the C-ROADS-CP/MODEL folder. You may put them elsewhere, but the default search location for output files is in the C-ROADS-CP/MODEL folder.

How can I delete old runs?

Go to the C-ROADS-CP/MODEL folder and drag the unwanted file into the recycle bin. Or go to “Load/Unload Run”, highlight a run on the left side of the window, under “Available”, and click the “Delete” button.

What is the best way to share a simulation run with another C-ROADS-CP user?

The most efficient means would be to send a copy of the “my run.cin” file that was saved into My Documents/C-ROADS-CP/MODEL/my run.cin. It is a small file for emailing purposes. The recipient places it in the C-ROADS-CP/MODEL folder and runs the simulation and selects “Load stored settings” from the opening screen it will be available for them to load. If they then wish to, then may create a copy of the data file by choosing “Save run”.

You could also send them a copy of the data file, “my run.vdf.” They could view this using the “Review runs(s)” button – which doesn’t allow the run to be altered – or they could use ‘”Update run” and view or modify the run further and create their own settings file using the “Save run” function.

What is the difference between the two types of graphs-the ones on the left and the ones on the right?

In the left pane are graphs mostly related to emissions profiles of the different gasses – inputs, more or less. In the right graph pane we have comparisons and impacts or effects – atmospheric concentrations, temperature change and sea level rise. Inputs on the left. Outputs on the right.

What are the countries in the 6 region mode? In the 15 region mode?

Countries in the 6 region mode are the United States, European Union, China, India, all Other developed countries and all Other developing countries.

The 15 region mode is comprised or the United States, European Union, Russia, Canada, Japan, Australia, South Korea, all other Developed non-MEF, Mexico, China, India, Indonesia, Brazil, South Africa, all other Developing non-MEF countries.

How can I see a bigger version of a graph?

Below each graph pane is a “Large Graph” button. Clicking the “Large graph” will open a window containing a larger copy of the graph above it. You may open a large graph from each pane. Within the large graph window, you may select other graphs to view. The graphs selections are the same as in the parent graph pane. You may also export the image of the graph and the data used to create the graph.

How can I view the numbers behind the graphs?

To see the numbers underlying a graph, click the “Data table” button. This brings up a window containing the graph’s data with choices to “Export all” or “Export Range”. There is also a check box to select to transpose the data before exporting it. When you click “Export all” the entire data set for the graph is placed on the clipboard ready to be pasted into an appropriate application of your choosing.

If you click the “Export Range” button you have an additional choice to select the date range of the data you wish to export. The default range is the same as the graph you are viewing. The data are placed on the clipboard for you to paste in your application of choice.

How can I make an Excel file of the numbers behind the graphs?

Select the graph from which you would like the numbers. Use “Export image/data” to open a dialog for the graph you are viewing which will allow you to export a picture or data in a variety of formats. The data export allows you to export data as an excel file.

An alternate method is to select “Data table” and choose either “Export all” or “Export Range” to place the data onto the clipboard. Switch to your spreadsheet program and paste the data into a worksheet.

How can I copy a graph into another program like Word or PowerPoint?

Select the graph you would like to copy. Click “Export image/data” to open a dialog for the graph you are viewing. Select the format in which you would like the image and click “Save…” to name the saved image file and place it in the location you wish. Select “Close” when you are finished saving images and or data from the graph.

I am in 15 region mode, but I only see four regions on the graph. How can I add more?

There are two ways to change the regions that are displayed on your graphs. In the C-ROADS-CP main screen select “Set graph defaults” where you can set the default country/regions you would like to view on graphs that display data “by country”. These default settings will be used each time you select "Create new run." You may reset them as you wish.

In the simulation control window you may override the default settings made in "Set graph defaults." Click the “Select regions” button to add or remove the regions displayed on the data by country graphs. This override remains effective until you end the current simulation run either by “Returning to main” or choosing “Reset to baseline”.

How can I look at fewer lines on one of the comparative graphs?

Click “Load/Unload run” to go to the Dataset Control dialog. The set of “Available” or viewable runs is on the left panel and the runs that are “Loaded” in your comparative graph are in the right panel. Double-click on a run in the “Available” column and it will move into the “Loaded” column and vice versa. You may also single click on a run name and then click on the arrow button between the columns to move runs back and forth between “Loaded” and “Available”.

You may also control the order of the runs in the graph. A single click moves any run to the top of the loaded column.

Dataset Control

How can I look at fewer lines on one of the graphs that shows multiple countries?

Each of the lines on a graph has a checkbox next to it. Un-checking the box will cause the line to be removed from the graph. The data label and checkbox remain; the graph line may be reactivated by checking the box again. The set of lines that are included is controlled from the “Select regions” or by the “Set graph defaults” buttons (see “I am in 15 region mode, but I only see four regions on the graph. How can I add more?”).

When I view a non-comparative graph, how can I select which of the runs I see?

In a non-comparative graphs you can tell which run you are viewing by the text at the bottom, “Showing values from run_name.vdf”. If you wish to view a different run, click the “Load/Unload run” button to go the Dataset Control dialog. The data set that is showing in a non-comparative graph is the one at the top of the “Loaded” list in the right panel. To move a run to the top of the list, click on it and it will rise to the top of the list. Click “Close” and the graph will show the run that is at the top of the “Loaded” list.

How do I change the Reference Scenario? What are my options for doing so?

This is under development and not available at this release. The intent is to allow the user to specify an alternative reference scenario to A1FI and have that used in the simulation and the reference scenario.

Are there macros in your Excel file?

There are a few simple macros that help refresh the Reference scenario settings should you wish to reset them to the default settings.

How can I input emissions via an Excel file?

The Excel file, “Emissions for C-ROADS-CPv2….xls”, contains two worksheets into which you may put data, “User 15 Region Inputs” and “User 6 Region Inputs”. You may specify your data inputs to the model using the area on the worksheet (15 Region inputs-- A3:P22 and 6 Region inputs-- A3:G22). When you have made the changes to the spread sheet, you must save the file so the simulation can read the changes from the file.

I changed the date in the "Emissions for C-ROADS-CP.xls" file but I don't see any difference in the simulation output.

When you make a change to the excel data file, “Emissions for C-ROADS-CP.xls”, it is important that the changes are to the correct sheet that corresponds to the aggregation level in the simulation you are using -- 6 region or 15 region. The excel file must be saved so that the simulation program can read it from the disk. The simulation must be started from the main menu from any of the three buttons, “Create new run”, “Update run” or “Load stored runs(s)”. Entering the simulation in these three modes reads the excel file information in to the simulator so that it may be used.

How can I input emissions via a graph?

If you select “Graphical” as an input method you can enter data by modifying a graph by dragging or by entering data points as pairs of “Year” and “Gtons CO₂/year”. You may also redraw the graph by clicking by the line and not on one of the points and slowly dragging a new line. This simultaneously creates the (year,Gtons CO₂ emissions/year) data points. Play around with it to get the hang of it. Hit reset to undo any mess you make.

Graph Lookup

I am setting emissions for countries one-by-one. How can I see all of them together?

Select the “Summary” button to produce a table of all the inputs in a row and column format. Numerical inputs may be entered in this table. Arrow keys, tab and Return will move from cell to cell.

What are other gases like methane doing in this simulator? Where do I change what they do?

You can set whether the emissions controls are controlling “CO2 equivalents” or controlling “CO2 only” in the NON-CO2 GHGs portion of the "Settings" pane. When ‘Set controls to regulate “CO2 equivalents”’ is selected, user inputs are in the form of CO2 equivalents. If you select 50% below a reference point (Ref year or Ref scenario) The 50% reduction will be applied across the GHG gases according to their prevalence at the Reference time.

If you choose Set controls to regulate “CO2 only", a 50% reduction will be applied only to CO2. All the other greenhouse gases will continue to grow according to the reference scenario.

What are the "goals" that I can set? Do they drive behavior"

You have the ability to set a goal for atmospheric CO₂ and temperature goal. These goals do not affect the outcome of a simulation run. They may affect how the user thinks about achieving the goal.
