To open files collected on the EM31-MK2 in the DAT31W files program, an EM31-MK2 file must be converted from the .R31 extension to the .G31 extension.
This is a common error that a user may not realize when dealing with EM31 survey results. Follow the directions below to properly convert these files.
1. Open the DAT31W program by clicking on its shortcut.
If there is no shortcut for your DAT31W program, click the Start Button on the computer and look under the heading “All programs” for it.
2. Pick the Convert Tab and select Convert Allegro/Archer EM31, ICE31, and ICE Files to DAT31W (G31) Format.
This is assuming that the user has already transferred the files to the computer via compact flash drive. Files can be transferred via serial cable. However, transferring with a serial cable tends to be difficult and not user-friendly.
3. Push the Input File Button and find the .R31 file that needs conversion.
This is an important reason that a user must give a file a relevant name to his or her files and directories. After selecting the Input File, push the Output File Button. The Output File Button asks the user to rename the new file and to save it to a directory. The old R31 file will be still around to access after creating the new converted file. Next, push the Convert Button. This will finish the process of converting the new file.
Newly converted files will not automatically open after being converted. If the user wants to open a newly converted DAT31W file, he must select the File Dropbar Menu from the DAT31W and click “Open Profile File”. From here, open the correct directory and select the G31 file that the user wants to view in the DAT31W program.
