Preferences

The Preferences option on the File menu, allows you to personalize your GM-SYS Profile Modelling environment. Preferences can be set for Files, the Model Window, and Miscellaneous items

Files

On Files, you may select default locations for your model files, backdrop images, and backup files generated by the AutoSave feature. With AutoSave enabled, GM-SYS Profile Modelling will save all open model files at the user-specified interval. In the event of a system failure or power outage, these files may be recovered during the next GM-SYS Profile Modelling session. The backup files are deleted when the program exits normally.

Model Window

The Model Window folder includes three sub-sections: Fonts, Anomalies, and Cross Section.

Fonts

The Fonts selection allows you to specify fonts used for each part of the GM-SYS Profile Modelling display.

Anomalies

The Anomalies selection allows you to set the colour, line style, and weight of each data component in the anomaly display. You may also specify whether each component's observed data and/or calculated curve is displayed by default when GM-SYS Profile Modelling opens.

Cross Section

The Cross Section selection allows you to configure the colour, line style, and weight of the line elements that comprise the Cross Section display. You may also set the number of decimal places to use when displaying density, susceptibility, or remanent magnetization values; these values apply to the Anomaly spreadsheet, as well.

Miscellaneous

On the Miscellaneous selection, you may set the maximum number of "Undos" and "Previous Views" saved for each model during a modeling session. You may choose the default units for GM‑SYS to use, which may be overridden on a model-by-model basis.

GM‑SYS version 4.6 introduced some extensions and changes to the .BLK, .SUR, and .GMS file formats. By default, GM‑SYS uses the new formats when saving a model. If backward compatibility is an issue, you must deselect the USE V4.6 FILE FORMATS box. Earlier versions of GM-SYS Profile Modelling will read these models, but will lose block colour/pattern information and may fail to load large models.
