The latest ioGAS™ version contains the following new features:

New User Interface

The re-designed ioGAS 7.0 user interface comprises groups of tools with related functionality arranged into ribbon toolbars.

The quick access toolbar provides access to any open plot window, the legend window and the help file with navigation between windows
and tools made easier via new keyboard shortcuts. Updated context toolbars include new right-click display modes, left/right toolbar display and double column toolbars. Choose from a range of Attribute Manager plot colour sequences with the capability to switch between colour sequences.

Pause/resume rendering operation

Pause updates to open plot windows while modifications are made to the Attribute Manager to batch operations together. Useful if one or more memory-intensive plots (such as a SPLOM) are open. Resume updates to refresh all plot windows to show the current state of the Attribute Manager.

Import acQuire Data

acQuireDirect for ioGAS link

Import data from acQuire GIM suite using the acQuireDirect API. Use existing selection files or create new selections.


Re-designed new calculation tool to allow a expression to be used within the same calculation. This enables calculations such as CIPW normative calculations to be created – see Normative Mineralogy in the Provided Calculations for examples. Use the new univariate calculation mode to replace null values in input variables with zero or the Quick Calcs for some automatic element, oxide and unit conversions.

Graph Updates

Downhole/line plots

Re-designed tools to enable up to 50 individual plots to be displayed in a single scrolling window. New downhole single trace (by variable) option to view the results for a single variable for multiple drillholes in the same plot window. Ability to save and re-use custom variable X-axis ranges between sessions and save preferred settings.

Centred ternary plot

Apply transformation to bring points toward the centre of the triangle when displaying compositional data in a ternary plot. Used when concentration of data points is in one or two corners making it difficult to detect any structure present in the data.

Reduced major axis regression algorithm

New algorithm added to XY/SPLOM regression line options and to the Analysis ribbon Regression tool.

Display 3D vectors

Overlay a 3D vector on each visible point on a 3D plot. The vector can represent any 3 quantities, such as vector magnetic data, or the first 3 principal components of a PCA.

Data Tools

Data view

Colour the cells in a variable column based on ranked percentile value.

Spider Plots

New Make variables from spider tool to write normalisation values for selected variables back to the dataset as new columns.

Column join

Join new columns of data or update data in existing columns using ID column.

Variable Maps

Expanded variable map thematic operations to include all Attribute Manager and custom (user) bin ranges. New 1, 2, 5, 10 times background thematic operation useful for the display of spider variable normalisation values.


Open templates with aliased data. Convert aliased data on-the-fly to required template variables. Access Provided and User templates via the new File ribbon or from the Open drop-down menu on other ribbons.
