Command line
You can run your GMDH Shell project in the background mode using the command line. In this mode GMDH Shell works like a command line tool without any interaction with the user.
The easiest way to run GMDH Shell in the background mode is to use the key /auto.
Example:
"GMDH Shell.exe" c:\Path\FileName.gsp /auto
Host commands
/auto | Runs specified project without user interaction. Example:"GMDH Shell.exe" c:\MyData\file.gsp /auto |
/save:FileName.gsp | Saves simulation results. Example:"GMDH Shell.exe" file.gsp /auto /save:result.gsp |
/semiauto | Semi-automatic mode. Same as /auto, but permits interaction with the user. |
/apply:FileName.gsp | Applies models already saved in the project file. Example:"GMDH Shell.exe" /apply:C:\MyData\project.gsp |
How to recover command-line options from a plug-in
- Look into
.gspproject file. Though the file is binary, for your convenience all plug-ins’ settings are kept there in human-readable XML. Find an appropriate section, e.g.<Storage file="BasePlugin" feature="1" description="Time series modeling">. Important: Despite XML section, .gsp file is binary, do not edit the file! - All settings stored in the XML section are configurable from the command line. For example, command line equivalent of
<task>future</task>is/pr.task:future./im— importer/pr— preprocessor/ca— solver/po— postprocessor/ex— exporter
- Some settings are stored in the so-called “shared storage”, accessible to several plug-ins. For example:
<Storage name="gs.prepro"><decompositionlimit>0</decompositionlimit>→/pr.gs.prepro.decompositionlimit:0
The plug-in may have some extra options not stored in the .gsp, but listed in the documentation.
Batch-mode export
/noexport | Prevents the export plug-in from exporting simulation results. |
/exportmodels | Exports models as Excel formula. Works for XLS/XLSX only, and some Shell's features do not convert to formulas. Example:"GMDH Shell.exe" file.gsp /auto /save:result.gsp /exportmodels |
Batch-mode exporter: Export forecast
/ex.file:FPath | Saves result to FPath. Example:"GMDH Shell.exe" file.gsp /auto /ex.file:C:\MyData\example.txt |
Import
/im.file:FPath | import file from path FPath. Example:"GMDH Shell.exe" file.gsp /auto /im.file:C:\MyData\example.xls |
Preprocess: Time Series Forecasting
/pr.backtest:n | Number of backtests to simulate = n. |
/pr.skip:n | Skip observations = n. |
/pr.gs.prepro.ts.shift:a,b,c /pr.horizon:a,b,c | Forecast horizons = a,b,c. |
Preprocess: Value prediction & Classification
/pr.unk:n | Number of unknown values = n. |
/pr.unit:sample | Unit of /pr:unk. Either sample or percent. |
Solver: Combinatorial
/ca.ncpu:n | Number of parallel threads |
Export module
Data Science and Load forecasting editions of GMDH Shell are supplied with an export module that outputs predictions in the command line mode. C++ source codes of the module - a CodeBlocks project is available in the installation directory “..\Plugins\ExportForecast-source.zip”.
The module automatically performs export of predictions when GMDH Shell is launched using the command line. Predictions are saved to simulation_result.txt in the project directory.
