 1. `[ERROR] No permision to create directory /scratch/...`  
 there are a couple ways to resolve this issue:
 * create a world writable directory named /scratch
-* create some other world writable directory and then define the environment variables RESULT_ROOT and PV_ROOT to point to that directory. If you want, you can create two directories to keep things separated. See [Directory Configuration and Structure] for more details.
