Export UBC DCINV2D/IPINV2D Format
Use the IP & Resistivity > Export > UBC DCINV2D/IPINV2D Format option, (geogxnet.dll(Geosoft.GX.IP.ExportUBC;Run)*), to export RES or IP data file for use in the DCINV2D/IPINV2D inversion programs.
UBC IP Export dialog options
RES Tab: DCINV2D Control File Parameters
Iterations: |
Set the iterations for the inversion. Script Parameter: IP_EXPORT_UBC.RES_NITER (default 30) |
Iterations restart: |
Set the iterations restart value for the inversion. Script Parameter: IP_EXPORT_UBC.RES_IREST (default 30) |
Chi factor: |
Set chi factor value for the inversion. Script Parameter: IP_EXPORT_UBC.RES_CHI_FACTOR (default 1.0) |
Mesh [file]: |
Version 3: Set the mesh file for the inversion. This value is not required. Script Parameter: IP_EXPORT_UBC.RES_MESH_FILE Version 5: The mesh for the inversion can be specified as a file, a value or simply default. This value is not required. Script Parameter: IP_EXPORT_UBC.RES_MESH_SELECTION(Default 0, File 1, Value 2) Script Parameter: IP_EXPORT_UBC.RES_MESH_FILE Script Parameter: IP_EXPORT_UBC.RES_MESH_VALUE |
Reference conductivity: |
Version 3: Set the reference model conductivity to begin the inversion at. If no value is input, then one is calculated using values in the "ResCalc" channel for each line. The resistivity values are converted to conductivities, then a value equal to the mean conductivity plus 2.5 standard deviations is used. Script Parameter: IP_EXPORT_UBC.RES_REFERENCE_CONDUCTIVITY Version 5: The reference conductivity can be provided as a file, a value, or simply default. The second parameter for the reference conductivity depends on this selection. The default is calculated as in Version 3. Script Parameter: IP_EXPORT_UBC.RES_REFERENCE_MODEL_SELECTION(Default 0, File 1, Value 2) Script Parameter: IP_EXPORT_UBC.RES_ REFERENCE_MODEL _FILE Script Parameter: IP_EXPORT_UBC.RES_ REFERENCE_MODEL _VALUE |
Alphas: |
Version 3: Set the alpha values for the inversion. Normally 3 values are entered. Note: No validation is done on these values; the numbers are output exactly as entered. Script Parameter: IP_EXPORT_UBC.RES_ALPHAS Version 5: Similarly to the above two parameters this parameter can be provided as a file, a set of 3 values, or simply default. Script Parameter: IP_EXPORT_UBC.RES_ ALPHAS_SELECTION(Default 0, File 1, Value 2) Script Parameter: IP_EXPORT_UBC.RES_ ALPHAS _ FILE Script Parameter: IP_EXPORT_UBC.RES_ ALPHAS _VALUE |
Weight file: |
Set the weight file for the inversion. This value is not required. Script Parameter: IP_EXPORT_UBC.RES_WEIGHT_FILE |
IP Tab: IPINV2D Control File Parameters
Iterations: |
Set the iterations for the inversion. Script Parameter: IP_EXPORT_UBC.IP_NITER (default 30) |
Iterations restart: |
Set the iterations restart value for the inversion. Script Parameter: IP_EXPORT_UBC.IP_IREST (default 30) |
Chi factor: |
Set chi factor value for the inversion. Script Parameter: IP_EXPORT_UBC.IP_CHI_FACTOR (default 1.0) |
[Conductivity file | Resistivity inverted Conductivity]: |
Version 3: Set the conductivity file for the inversion. By default the file output by the DCINV2D program is used (dcinv2d.con). Script Parameter: IP_EXPORT_UBC.IP_CONDUCTIVITY_FILE Version 5: The resistivity inverted conductivity can be provided as a file, a value, or set to none. The second parameter for the reference conductivity depends on this selection. The default is calculated as in Version 3. Script Parameter: IP_EXPORT_UBC.IP_CONDUCTIVITY _SELECTION(Default 0, File 1, Value 2) Script Parameter: IP_EXPORT_UBC.IP_CONDUCTIVITY _FILE Script Parameter: IP_EXPORT_UBC.IP_CONDUCTIVITY _VALUE |
Mesh [file]: |
Version 3: Set the mesh file for the inversion. By default the file output by the DCINV2D program is used (dcinv2d.msh). Script Parameter: IP_EXPORT_UBC.IP_MESH_FILE Version 5: The mesh for the inversion can be specified as a file, a value or simply default. This value is not required. Script Parameter: IP_EXPORT_UBC.IP_MESH_SELECTION(Default 0, File 1, Value 2) Script Parameter: IP_EXPORT_UBC.IP_MESH_FILE Script Parameter: IP_EXPORT_UBC.IP_MESH_VALUE |
Initial model [file]: |
Version 3: Set the initial conductivity model file for the inversion. This value is not required. Script Parameter: IP_EXPORT_UBC.IP_INITIAL_MODEL_FILE Version 5: The initial conductivity can be provided as a file, a value, or simply default. The second parameter for the reference conductivity depends on this selection. The default is calculated as in Version 3. Script Parameter: IP_EXPORT_UBC.IP_INITIAL_MODEL _SELECTION(Default 0, File 1, Value 2) Script Parameter: IP_EXPORT_UBC.IP_INITIAL_MODEL _FILE Script Parameter: IP_EXPORT_UBC.IP_INITIAL_MODEL _VALUE |
Reference model file | Reference Chargeability: |
Version 3: Set the reference model file for the inversion. This value is not required. Script Parameter: IP_EXPORT_UBC.IP_REFERENCE_MODEL_FILE Version 5: The reference chargeability can be provided as a file, a value, or simply default. The second parameter for the reference conductivity depends on this selection. The default is calculated as in Version 3. Script Parameter: IP_EXPORT_UBC.IP_REFERENCE_MODEL_SELECTION(Default 0, File 1, Value 2) Script Parameter: IP_EXPORT_UBC.IP_ REFERENCE_MODEL _FILE Script Parameter: IP_EXPORT_UBC.IP_ REFERENCE_MODEL _VALUE |
Alphas: |
Version 3: Set the alpha values for the inversion. Normally 3 values are entered. Note: No validation is done on these values; the numbers are output exactly as entered. Script Parameter: IP_EXPORT_UBC.IP_ALPHAS Version 5: Similarly to above this parameter can be provided as a file, a set of 3 values, or simply default. Script Parameter: IP_EXPORT_UBC.IP_ ALPHAS_SELECTION(Default 0, File 1, Value 2) Script Parameter: IP_EXPORT_UBC.IP_ ALPHAS _ FILE Script Parameter: IP_EXPORT_UBC.IP_ ALPHAS _VALUE |
Mesh file: |
Set the weight file for the inversion. This value is not required. Script Parameter: IP_EXPORT_UBC.IP_WEIGHT_FILE |
