The files 'Geometry.py' and 'PeptideBuilder.py' constitute the PeptideBuilder library. They need to be placed into the search path of your python installation.

The file 'simpleExample.py' is a brief example script demonstrating basic use of the PeptideBuilder library.

To test whether your installation works properly, run the script 'unitTests.py' and compare the resulting output to the files in 'unitTests.expected'. On a unix machine unix, the shell script 'runUnitTests.sh' will do that for you. If the shell script doesn't find any differences (prints out only empty lines) then everything is working correctly.

Note: Apparently some versions of Biopython add a line containing 'END' to end of created PDB files, and this breaks the unit tests. If all your unit tests fail, check whether that's the reason why. Simply check manually whether the files in folder 'unitTests.expected' look like the files generated by the script 'runUnitTests.sh'.

The script 'evaluation.py' reproduces the results presented in Table 1 of the PeptideBuilder manuscript.
