Import geochemical datasets from databases or from mass spectrometer output files, reorder and normalize to produce geochemical spider diagrams.

This XOP wraps libSVM to provide Support Vector Machine-based classification, regression, and novelty detection in IgorPro.
For a detailed desccription of the algorithm, see https://github.com/cjlin1/libsvm

To install, simply copy the applicable XOP (macOS or windows, 32 or 64 bit) and SVM Help.ihf to the respective Igor Extension folder. SVM has been tested (and should work) on Igor7 on macOS and Igor 6.37 and Igor7 on Windows7.
The XOP adds two operations, SVMTrain and SVM classify, to IgorPro. For a detailed explanation if the syntax, see the included help file.

GCscatter (Gizmo Control for scatter plots) makes it easy to manipulate 3D scatter plots by collecting commonly needed controls in a convenient panel. Advanced settings and more info are available in the Gizmo Control menu.

Controls include: axis on/off, labels, ranges, ticks; window position and zoom; bonds, symbols and sizes, etc.

The control panel can be minimized, and is hidden when the Gizmo window is not active. When you reactivate it, the panel reappears. Multiple scatter gizmos can be used.
