|
10 A penalty score of 0 means that the corresponding valence is optimal.
|
|
11 Note that the first matching entry is taken as the final atom type.
|
|
12
|
|
13 Note that in the SMARTS strings we use atomic numbers rather than symbols (e.g. #8 instead of O).
|
|
14 The reason is that wrongly assigned aromatic bonds in the input would lead to failure to identify the
|
|
15 right rule!
