About some question on LPJ model and the package #48

Dear developer, thank you for your great work! Recently, l just started to study LPJ-GUESS model. l have some question about the package, and l hope you can help me. 1, l have compiled the LPJ-GUESS and there are some files in the build folder, but l do not which one to use create a link to the guess executable, the guesscmd or guess? l am in the window system. 2, I'm confused about ‘gridlist.txt’, In this document, we should import the longitude and latitude of the simulated region？ or all the grid size in the analyzed region? Finally, l take the liberty of asking for a request: can you share with me the data used in this package test? . l think that can help me understand the model. Thank you for you again!

Hi AbelDavid,

below you find the answers to your reported issues. Next time please consider reporting each issue separately, it makes it easier for us to answer and for everyone else to follow the issue.

Issue 1:

1, l have compiled the LPJ-GUESS and there are some files in the build folder, but l do not which one to use create a link to the guess executable, the guesscmd or guess? l am in the window system.

You should use the name of the executable file you have. In Windows is guesscmd.exe.

Issue 2:

I'm confused about ‘gridlist.txt’, In this document, we should import the longitude and latitude of the simulated region？ or all the grid size in the analyzed region?

The gridlist.txt is the text file having the coordinates of the grid or the grid IDs. The formatting is given by the model not by the package. You can find an example file in the package by typing: mainDir <- system.file("extdata", package = "rLPJGUESS") list.files(mainDir) readLines(file.path(mainDir, "gridlist.txt"))

This code lines are from the package vignette. You should be able to access it by typing vignette("rLPJGUESS") or at this link https://cdn.rawgit.com/biometry/rLPJGUESS/80a8ac8a/rLPJGUESS/vignettes/rLPJGUESS.html

rLPJGUESS is an interface for the model LPJ-GUESS. If you have questions regarding the model, you might consider contacting the model developers.

Dear Rasilgon, thank you for your detailed explanation. when l try to run test data in the rLJPGUESS package, l found the test data in the test folder in empty. l take the liberty of asking for a request: can you share with me the data used in this package test?

Hi AbelDavid, I apologize for my late reply. The test data folder is meant for internal testing only, therefore it does not include forcing or input data. If you are still interested in trying out the package, have a look at our recent publication on Environmental Modelling and Software "An R package facilitating sensitivity analysis, calibration and forward simulations with the LPJ-GUESS dynamic vegetation model" (https://www.sciencedirect.com/science/article/pii/S1364815217310629). You will find detailed instructions and code to perform several tasks there, as well as the link to the data used in all the simulations. I hope this helps!
