Name of the GCAM scenario

[nanhung]

The name of the GCAM scenario scen_name can not arbitrary define in m1_emissions_rescale() . Here is my code ,

data.wd <- system.file("extdata", package="rfasst")

db_path <- data.wd
query_path <- data.wd
db_name <- "database_basexdb_5p3_release"
prj_name <- "testJOSS.dat" 
#scen_name<-"Reference_gcam5p3_release" 
scen_name<-"Ref_gcam5p3_release"  # cannot use the arbitrary name? 
queries<-"queries_rfasst.xml" 

I got the error output as,

The error might come from rgcam package at this line

prj <- rgcam::addScenario(conn, prj_name, scen_name, paste0(query_path, "/", queries), clobber = F)

@nanhung the scenario name cannot be arbitrary, it has to be one of the scenarios of the database you are connecting with. This is associated with the structure of the rgcam package, in which you create the connection with your scenario in two steps:

conn <- localDBConn('/path/to/dbs', 'my-gcamdb_basexdb') When you run this, the console reports the scenarios on the DB you are connecting with.

prj <- addScenario(conn, 'my-project-name.dat', 'my-scenario-name', 'my-batch-queries.xml') In this step, you add the scenario you want to the project.

• my-project-name.dat can be an arbitrary name to save the project in your directory, so that in a next time you only need to prj<-loadProject("my-project-name.dat")
• my-scenario-name is the name of the scenario and should be exactly as it is on the DB you have made the connection with.
• my-batch-queries.xml is the query file (+query path if needed) you are using in the analysis (queries_rfasst).

I will clarfity this issue on the dicumentation vignettes.

Thanks! It will be easy for the user if they do not need to assign the my-scenario-name since it has a certain naming rule to follow.

Thanks @nanhung ! Just to clarify, each GCAM simulation has an associated name that will be user defined (no naming rule), so that's why rgcam is structured like that.
