 User can run SEAMCAT from Command Line which helps if you want just to run simulation and get the results. This feature is useful to run SEAMCAT simulation on number of already prepared workspaces, or if resources of the computer is an issue. In Command Line SEAMCAT just run the simulation on already prepared workspace and Graphical User Interface is not launched.  Find below some tips for using SEAMCAT in a command line environment. 

A command line launch of SEAMCAT (i.e. without GUI) is possible using the same seamcat.jar file that has been you have downloaded.  From the command line with a workspace file called "myWorkspace.sws" the following command will It will launch the workspace and save the results in myWorkspace.swr by default.

 

java -cp seamcat.jar org.seamcat.CommandLine myWorkspace.sws 

Several options are possible. The result file name can be changed by using the option: result=otherNamemyWorkspaceResults.swr and the number of events can be specified by using the option: events=12345. The example below uses all these parameters: 

java -cp seamcat.jar org.seamcat.CommandLine

Default-ws.sws result=commandLine.swr events=200000

myWorkspace.sws result=myWorkspaceResults.swr events=12345 


 you will see the following when setting 12 events:

$ java -cp seamcat.jar org.seamcat.CommandLine myWorkspace.sws result=myWorkspaceResults.swr events=12

Total simulation duration:           0.033  second

Event generation duration:           0.03   second

Calculation rate:            400    events/second

x.1.3 Extracting vector results from the workspace results

Once your simulation is done, you can either open the .swr results file from the SEAMCAT GUI or it is possible to extract the vector results in a separate file directly from command line.

java -cp seamcat.jar org.seamcat.CommandLine myWorkspaceResults.swr > myVectorResults.txt  

Running the above code will generate a new file in .txt format as shown below.

The vector results will contain the following vectors: the number of events, iRSSunwanted, iRSSblocking, the dRSS vector and the iRSSunwanted+blocking.

Afterwards you can use some command like cut to clean-up the data you want. For instance, in Linux (Unix) environment, you can use cut command. For example, if you are only interested in the “number of events” and “iRSSunwnated”, you should use the following command:


cut -d$'\t' -f1,2 myVectorResults.txt > newFile.txt

In Windows environment you can use command:

FOR /F "tokens=2-3 delims= " %i in (myVectorResults.txt) do @echo %i %j %k
