Extracting data from GCF files

The easiest way to extract data from a GCF file is by using the “View” mode of Scream.

  • From the command line, type scream -view filename where filename is the path to the file containing the GCF data
  • Hold the shift key and the left-mouse button, then drag over the area of interest until the screen displays only the data you want.
  • Release the shift key and select Save from the pop-up menu.

You can save the data in any of the formats that Scream supports.

 

It is also possible to extract data from a GCF file using GCFinfo.

  1. Install GCFinfo on your PC.
  2. Right-click on the GCF file and select View.

    Select View → Time Section or use the mouse to zoom in until the window displays only the data you want.
  3. Select File → Save As… and choose a name for the new file.

You can also save in the other formats supported by gcfinfo, allowing quick and easy extraction of data for analysis in other applications.
