Interactive Scatter Analysis

Use the Interactive Scatter Analysis option (Geosoft.uxo.gxnet.dll(Geosoft.GX.UXO.UxaLaunchScatterAnalysis;Run)*) to setup the source database and run the Scatter Analysis tool, which is used to show the targets that are part of a selected cluster.

Scatter Analysis dialog options

Source database

Select the source database.

Script Parameter:UXANALYZE.SOURCEGDB

Group

Select the group name, which will be set as the current group in the database and will be the only selected group.

Script Parameter:UXANALYZE.SOURCEGROUP_SCATTER

Mask channel - all sources

Select the mask channel for all the sources.

Script Parameter:UXANALYZE.TARGETMASK2

Size channel

Select the source size channel associated with a certain gate. For example, UXA_SIZE8 is the 8th element of UXA_SIZE channel.

Script Parameter:UXANALYZE.TARGETSIZE_SINGLE

Decay channel

Select the source decay channel associated with a certain gate. For example, UXA_DECAY36 is the 36th element of UXA_DECAY channel.

Script Parameter:UXANALYZE.TARGETDECAY_SINGLE

Match channel suffix

Select the match channel suffix.

Channel suffix will be added to "UXA_LmStat_" and "UXA_LmID_" prefixes to create match statistics and match ID channel names.

Script Parameter:UXANALYZE.LM_SUFFIX

Match statistics channel

Read only field - contains match statistics channel name.

Match statistics metric shows the degree of match between a target and the items in the signature library, so its size would be the same as the number of items in the signature library.

Match ID channel

Read only field - contains match ID channel name.

Each item in this channel shows the indices of the items in the signature library associated with the match ID values.

Self match cluster threshold

Specify the threshold for the metric match to consider the item a self-match and similar to other items in the source database.

Default value is 0.95.

Script Parameter:UXANALYZE.MATCH_THRESHOLD

Application Notes

When the [OK] button is selected, the mask channel will be copied to UXA_MASK_SCATTER channel, which will be set as the mask channel in the Scatter Analysis tool and which will be used to plot only the targets in each cluster.

The following steps demonstrate how to highlight a Self-match cluster:

  1. Select a target in the interactive Scatter Analysis window.
  2. Click the right mouse button and from the pop-up menu, select Highlight Self-match Cluster. This will update the mask channel for the Scatter Analysis (UXA_MASK_SCATTER), deselecting all the targets that are not part of the cluster represented by the selected target.
  3. Click the Refresh the data () button on the Scatter Analysis tool to update the plot and apply the new mask values. The default is to display the targets that are part of the selected cluster in red, and the targets that are not part of the selected cluster in grey.

*The GX tool will search in the "gx" folder. The GX.Net tools, however, are embedded in the Geosoft.uxo.gxnet.dll located in the bin folder. If running this GX interactively, bypassing the menu, first change the folder to point to the bin folder, then supply the GX.Net tool in the specified format.
