To create a time animated model in Surfer each time point will need to be modeled separately and then exported to GIF for use with an online animated GIF creator. This can be done fairly quickly using a script like the one below which creates a grid, contour map, and GIF for each DAT file in a specified directory.
If you would find a built in time-animation feature in Surfer helpful with your work, please let us know.
To run this script:
- Copy the script below, or download the attached BAS file: GridContourExportLoop.bas.
- In a Windows Explorer window, navigate to C:\Program Files\Golden Software\Surfer.
- Double click on Scripter.exe to launch Scripter.
- Press Ctrl+A to select all of the existing lines then press DELETE.
- If you copied this script, press Ctrl+V to paste it into Scripter. If you downloaded it, click File | Open, select the BAS file from your downloads directory, and click Open.
Update the User-defined variables section with your own files and preferences.
- Click Script | Run to run the script.
