Outputs in iLand are per default created as a SQLite database. Every type of output is represented by one table within this output database. Thus, the results of one simulation run are contained in one single file. Each iLand output database contains a small table named "runinfo" which stores the timestamp when the simulation was started, and iLand version information.
Alternatively, individual outputs can be configured to generate data tables as a text file instead of a table in the output database.
Basically, there are two options:
- reuse a database: in this case every run will overwrite the preceding run. This is an option when still "playing around".
- create a database for each run: this is clearly the option of choice for larger simulation jobs.
The filename of the output-database is defined by the home.database.out key in the project file. If this key contains a normal filename, option 1 is pursued. If you want to go with option 2, a special syntax can be used for the filename (e.g. projectX_\$date\$.db), where the string between the \$-signs is replaced by a time stamp value (e.g. "20091021_143059"). See also iLand console if you want to control the output location and filename for larger simulation batch jobs.
