Introduction

In this part information are focusing on functionalities related to generation of text input files for the STICS model.

Generated files will be directly usable for running the model with SticsOnR package functions. See the documentation here.

Converting JavaSTICS workspace files

For using the model directly neither using the JavaSTICS graphical interface nor the run_javastics function interface, we provide a function, gen_usms_xml2txt, for converting JavaSTICS XML files to STICS text files from a JavaStics workspace.

Then, the model can be run using the run_stics() function from SticsOnR

Observation files may also be copied if they have a standard name corresponding to a usm name and a .obs extension. If not, they must be renamed to do so.

# Specifying the JavaSTICS folder
javastics_path <- "/path/to/JavaSTICS-1.5.2-STICS-10.1.0"

# Specifying a workspace as a subfolder of JavaSTICS
workspace_path <- "example"
# or an absolute path to an external folder
# workspace_path <- "/path/to/javastics/workspace"

# Specifying an output folder path
output_path <- "/path/to/output/folder"

Converting files into separated folders (one per usm)
