Structure Extents for Specified Structure

You might want to use this option rather than calculate the extents for all structures if the file you are dealing with is very large. The extents calculation for all structures can be time consuming on very large files.

Using GSCAN in parallel mode

If you wish to run gscan in parallel (running it on multiple files and the same time), use the following command line:
