ClicSANDs Output File Defenition

[trevorb1]

When using ClicSANDs to create a datafile, it seems like there is an issue where time-independent parameters that use only the default value definitions are not being written correctly. This may be even more specific to just where default values are zero, but Im not sure on that.

For example ModelPeriodExogenousEmission is defined in ClicSANDs as

And the definition looks correct in the ToDataFile tab:

However, when you look at the output data file it's defined as:

While this doesn't make a difference for processing the datafile with GLPK (or at least not that I can see), it is throwing an error if trying to convert it with otoole. Specifically, the amply library is having trouble processing it. If we comment out the data (such as shown below) or add in the zero data, otoole will work fine.

param ModelPeriodExogenousEmission default 0 :=
;

Is there a way we can update ClicSANDs to print out the full definition in the text file (ie. the definition shown below)?

param ModelPeriodExogenousEmission default 0 :
EMIC02 EMICH4 EMIFGA EMIN2O EMIREN :=
RE1 0 0 0 0 0
;

Hello Trevor,

May I know the version of clicSAND you are using?

Hi @ReemaMohanty! I'm using ClicSANDs 3.0 for Windows which I downloaded from here. But this issue also exists on the Mac version.

Also, something I just realized, this bug is only introduced when reformatting the output text file. For example, when you generate the cloud input data, you get two datafile; Base_SAND.xlsm.txt and Base_SAND.xlsm.txt.cloud_data.txt. With the second one (*.cloud_data.txt) being the one we use as it removes all default values to reduce file size.

However, in the Base_SAND.xlsm.txt, which includes all default values, the ModelPeriodExogenousEmission parameter is defined correctly as shown below.

So I guess the error is being introduced when reformatting this file?

As found by @ReemaMohanty, it seems like the sands_filter.py script (see here) is what needs to get updated. It is a little odd that this script is only found in the mac ClicSANDs repository, and not also here.
