31.1 Create a Format Record
Creating a Format Record allows PEcAn to levereage Meta-data about your data in order to properly handle it. It allows you to define what type of file it is by defining it’s mimetype (i.e. text, netcdf,rds, etc.), define what information is hel in the header of your file, and how many lines need to be skipped within the file to get to ge to the header. To create a format record
* Navigate to the Formats table in BETY under the RUNS tab.
* Click "New Format"
* Fill in the appropriate information to define your files format
* Click "Create"PEcAn has a single xml configuration file. This fill will dictate what models to run, where, with what input files and for how long. Each model has its own configuration file as well.
31.1.1 PEcAn Configuration Files
This file is often called pecan.xml. The system will try to find this file in the following locations:
* Passed in when calling R with –settings
* Passed in to read.settings() function * PECAN_SETTINGS environment variable * File called pecan.xml in the current working folder
Once any of these are loaded it will try to locate a pecan.xml in the outdir specified in the loaded file.
