GRAPLEr |
The function allows user to submit an experiment to a GRAPLEr service running on endpoint graplerURL. The input files should be placed in ExperimentRootDir.
{: .text-justify}User can optionally run a script to filter the results by extracting one or more variables from the output file “output.nc”.
If user desires to run a script, user has to include a file “FilterParams.txt” in the input working directory, which should be placed in a folder “FilterParams”. This file should contain the variables and their corresponding depths.
{: .text-justify}Sample contents of the file should be as below:
{% highlight ruby %} VarsToAnalyze = c('OXY_oxy','OGM_doc') Depths = list(NULL,c(1,5,10)) {% endhighlight %}
Additionally user also has to provide the name of a filter script which is already present on the server in the below path:
{% highlight ruby %} “/datadrive/Graple-flask/GRAPLE_SCRIPTS/Filters” {% endhighlight %}
A sample script file can be downloaded by clicking on the link below:
If a filtername is not provided, the directory structure of experiment root directory should be similar to the below figure:
{: .center-image }
Example:
{% highlight ruby %} graplerURL<-“http://graple-service.cloudapp.net” expRootDir<-"c:/ExperimentRootDir" setwd(expRootDir) expId1<-GraplePostProcessRunExperiment(graplerURL, expRootDir) {% endhighlight %}
If a filtername is provided, and the experiment root directory has a folder “FilterParams” which consists of a file “FilterParams.txt” (An R script with the “filtername” should be present on the server), then both these files are merged to form a filter “PostProcessFilter.R” which will be used to filter the results.
{: .text-justify}The “FilterParams.txt” file consists of the parameters required for the filter (filtername - chosen by the user). The directory structure should be similar to the below figure:
{: .text-justify}{: .center-image }
Example:
{% highlight ruby %} graplerURL<-“http://graple-service.cloudapp.net” expRootDir<-"c:/ExperimentRootDir" filterName <- "Filter1.R" setwd(expRootDir) expId2<-GraplePostProcessRunExperiment(graplerURL, expRootDir, filterName) {% endhighlight %}
However, if a filtername is provided and experiment root directory does not have a “FilterParams” file, then it is expected that the filtername chosen has the parameters required and it will be used as a filter directly.
