We are pleased to announce the release from the CSIRO of the NEW TSG Suite updates to TSG Pro v5, TSG Core v6, TSG Lite v1 and TSG Viewer v6.

All current TSG users are eligible to download this update and make use of the new functions and enhancements. Below, we outline these new functions and how to use them. In another release over the next couple of months these new functions will be fully documented in the TSG user manual.

If you have not yet upgraded to TSG Pro 5 or Core 6 then here is an opportunity to get up to date with the latest version and make use of the new functionality. It could save you hours or even days of processing and analysis time!  We would be happy to provide you with a trial version to test out.

Download the new update now!

Click here for details of how to use some of the new functions. All will be documented in the user manual as soon as possible.

To install the update, if you already have a current TSG licence:

1.      Download the new set up file onto your PC.

2.      Run the set up file which will install the new TSG update over the top of the old version.

3.      Open TSG and it should run as normal.

4.    Contact us for information on a trial or upgrade.

New TSG Functions for July 2008

Correction to spectralon for ASD spectra (new to all TSG options): There is now an option in the final page of the TSG file creation wizard called "Final correction spectrum" that allows you to choose an absolute reflectance spectrum of spectralon for your ASD spectra. Recommended for all ASD spectra (i.e. from Labspec, Fieldspec or Terraspecs), but NOT for any other spectrometers unless they also calibrate on spectralon.

Floater Aux match settings (new to all TSG options): Users can now set up the floater aux match settings in the Settings panel (under the Edit menu) to be the same as the settings in an Aux match scalar.  This means that the floater can display exactly the same matches to the Aux match scalar output and users can then compare the matched spectra to directly assess goodness of fit.  For example AusSpec's GESSL library spectra can be attached as an aux file and then overlaid with your project spectra to compare the output of the matched GESSL mineral assemblage classes.

Aux match noise threshold option (new to all TSG options): TSG users can now specify a noise threshold which clips noisy parts of the spectrum to remove particularly noisy sections in the matching process.

Merge TSG files (new to TSG Core): Users can now combine a series of TSG files along with their scalars to create a *single* TSG file.  This offers fantastic flexibility!

Grid option in scatter screen (new to TSG Core): As well as the existing scatterplot and histogram plot options in the scatter screen, users now can grid a scatterplot to create a plot of point density in the scatterplot.

TSG New Functions posted in March 2008

TSG Scalar Groups (new to all TSG options):

o       TSG now has a “Groups” structure for scalars, similar to the way that files are organised in folders.  This is a useful way of organising and finding your ever growing list of scalars.

o       “Scalar Names and Groups” dialogue: This dialogue allows you to organise existing scalars into different groups if necessary. You can also edit their names if you are not happy with the original name.

o       All existing TSG files will be automatically organised into the scalar group structure. You can then move the scalars around to more appropriate groups if necessary. 

o       New scalars can be assigned to a group selected by the user.

Log screen class edit (new to TSG Pro): 

o       All class scalars can be edited in the Log Screen now as well as in the Scatter Screen.

o       This makes editing any Aux match outputs, such as the GESSL results, or other (perhaps imported) class data easy. It is possible to select a series of samples and assign them to another class item, or create a new class item to assign them to. 

TSA Allowed Mixtures (new to TSG Pro and Core):

o       This is a setting that allows you to set which minerals you want active in the TSA results and also which minerals are acceptable to occur with each other.

o       For example you may wish to disallow co-occurrence of illite with muscovite, or switch off opal from all outputs.  TSA would then display the next nearest fit.

VLines (new to TSG Pro and Lite):

o       it is now possible to label diagnostic absorption features on the Spectrum and Floater screens to highlight them as you scroll through a series of spectra. 

o       You can also create a small txt template file of the line positions for a particular mineral phase.

Metadata (new to all TSG options): 

o       This option is a precursor to the future data basing capabilities of TSG and allows you to enter details of the project area and drill holes represented in your TSG file.
 

Class Scalar Description field (new to all TSG options): 

o    Each class-item name can now be accompanied by a description. 
 

White background for screen displays (new to all TSG options):

o      The traditional black screen background can be changed to white now if you prefer.
 

Linescan colour correction (new to TSG Core):

o    This option allows you to apply a colour stretch to all the linescan data in a HyLogging (HyLogger and HyChip data set).

Masking in the Interactive Depth editor (new to TSG Core): 

o     This is a new option in the Interactive Depth Editing function (used in the Tray Screen for manually correcting core depths in HyLogging data sets)  whereby the ITDL scalar can be used as a template for creating a Mask scalar of tray edges and wood blocks. This mask can then be applied to all scalars in the TSG file to null out non-core material.

Floater co-occurrence mode (new to TSG Core):

o      A new mode in the floater to allow the user to explore the co-occurrence of two class scalars, including the TSA scalar results.  Plots the results in a co-occurrence matrix plot.

Tray Screen (new to TSG Core): 

o     Easy scrolling through core tray images in the Tray screen, there are a number of little arrow buttons to allow you to move between the tray images more easily.
