Example

1. Make a new directory and put your pdb file in it.

2. Make a template settings file in that directory:

   powder -t > settings.cfg
   

3. Edit at least the first five values in the settings file on the right hand side of the "=" signs.

   Important - Don't change the names on the left of the "=" signs because the left hand side names have meaning.

4. Run powder with the config file you edited:

   powder settings.cfg
   

Testing Setup

You can test your setup in the test directory with the command:

./powder-test test.cfg

This allows testing after development without the need to build and install.

The -d flag is also available to prevent powder from running ccp4 and xprepx during debugging.
