Recalculate Derived Data
Use the Recalculate Derived Data option, (geogxnet.dll(Geosoft.GX.IP.RecalculateDerivedData;Run)*), to recalculate the channels that are calculated on import.
Recalculate Derived Data dialog options
Vp channel |
The input receiver potential difference channel. It defaults to "Vp" if the channel exists in the database. Script Parameter: IPRECALC.VP_CHANNEL |
Current type |
The current can be provided either as a channel (the Channel option) or as a constant (the Constant option). Script Parameter: IPRECALC.CURRENT_TYPE [1 – channel (default), 0 – value] |
Current channel or Current value |
If you selected the channel option above, you will be prompted to provide the channel name. Otherwise, you will be prompted to supply a single current value. If the Vp data has already been normalized to the current, enter a value or 1. Script Parameter: IPRECALC.CURRENT_CHANNEL or IPRECALC.CURRENT_VALUE |
Recalculate N |
Check this option to recalculate the pseudo-depth index channel. Script Parameter: IPRECALC.CALCULATE_N [1 – checked (default), 0 – unchecked] |
Recalculate XYZ |
Check this option to recalculate the 3D location of the pseudo-section plot point. Script Parameter: IPRECALC.CALCULATE_XYZ [1 – checked (default), 0 – unchecked] |
Output metal factor channel |
The channel name of the calculated metal factor values. If the channel already exists, it will be overwritten. See Import IP Data for "metal factor" formula. Script Parameter: IPRECALC.MF_CHANNEL |
Output average IP channel |
The channel name of the calculated average IP. If the channel already exists, it will be overwritten. See Import IP Data for "Ip_Avg" formula. Script Parameter: IPRECALC.AVGIP_CHANNEL |
Output apparent resistivity channel |
The channel name of the calculated apparent resistivity values. If the channel exists in the database, it will be overwritten. See Import IP Data for the apparent resistivity formula. Script Parameter: IPRECALC.APPRES_CHANNEL |
Lines to process |
The database lines to be processed; the options are: the selected lines (the default), the currently displayed line, and all the lines. Script Parameter: IPRECALC.LINE_SELECTION [ "A" : All lines, "S" : Selected lines (default), "D" : Displayed line] |
Transmitter 1 & Transmitter 2 |
Transmitter 1 is mandatory for all IP configurations. In the Transmitter 1 tab, provide the X, Y channels (for 3D arrays) or the Along-line channel (for 2D arrays). If the configuration supports a second transmitter, proceed to enter the coordinates of Transmitter 2. Script Parameters: IPRECALC.Tx1X, Tx1Y, Tx1Z IPRECALC.Tx2X, Tx2Y, Tx2Z |
Receiver 1 & Receiver 2 |
Receiver 1 is mandatory for all IP configurations. In the Receiver 1 tab, provide the X, Y channels (for 3D arrays) or the Along-line channel channel (for 2D arrays). If the configuration supports a second receiver, proceed to enter the coordinates of Receiver 2. Script Parameters: IPRECALC.Rx1X, Rx1Y, Rx1Z IPRECALC.Rx2X, Rx2Y, Rx2Z |
*The GX.NET tools are embedded in the geogxnet.dll file located in the "...\Geosoft\Desktop Applications \bin" folder. If running this GX interactively, bypassing the menu, first change the folder to point to the "bin" directory, then supply the GX.NET tool in the specified format. See the topic Run GX for more details on running a GX.NET interactively.
