After starting a new inversion project the import function will be available on the Explorer menu. Select Import Syscal file from the Schedule tree.
The import data file workspace appears and the Quadrapoles button is selected. At the bottom of the frame the IMPORT SYSCAL BIN menu is available. Choose the type of import: Ignore these commands if you are going to link the imported bin file to the original sequence file (see below). Click the import Syscal file button to open the Windows command dialog and select the IRIS Syscal bin file with the resistivity and/or IP data-set to import. A new window appears and two views are available: the "field Data" view for the quadrupoles and data and the Electrodes view for the coordinates of the electrodes. A known issue is that in the Syscal bin format the
four electrodes of each quadrupole are expressed in terms of
cartesian coordinates and not using the four numbers that identified the
electrodes during the acquisition. So for three-dimensional arrangements (in
particular for "strange" geometries) the electrodes numbering that ERTLab
derives can be different from the one used in the field to acquire the
data-set. To import finally the file choose the type of import option
in the left part of the Import Data file window and click the OK button: For quadrupole arrays using remote poles, the exact location of the reference electrode can be specified by the user in the correspondent text box. |
