Math Expression Builder
The new Math Expression builder helps leverage the power of the math engine by making it easier to create and use math expressions.
To build a simple expression to subtract two channels, you can:
- enter the channel names and create my expression
- use channel variables and select the channels from the dropdown lists
The math expression builder has many functions, including:
- Frequently used (Logical, Logs, and Exponents)
- Trigonometric functions
- Date functions
- Time functions

You can load saved expressions in channel, grid, and voxel math tools to build large, complex expressions easily.

FAQ
Can I open workspace files (*.gws) in Oasis montaj 7.0?
Project files (*.gpf) have replaced workspace files (*.gws) in Oasis montaj.
You can convert workspace files used in Oasis montaj prior to version 6 by opening them:
- Select File > Project >Open > File of Type as Workspaces (*.gws).
- To convert the workspace into a new Oasis montaj project file, select Yes when prompted.
- Oasis montaj converts the workspace file to a project file and transfers all associated workspace information to the new project file. The workspace file remains untouched, so that you can open it in previous versions.
For more FAQs on the new release, see the Support FAQ.
