Structure Checker is a chemical validation tool detecting and fixing common structural errors or special features that can be potential sources of problems. Structure Checker works with predefined checking elements and it is possible to choose which ones should be considered when runs a check.
This function gives a text-type warning about the specified structural error.
This function gives a structure-type warning about the specified structural error.
This function offers a fixed structure.
Returns TRUE if any atom in the molecule has valence error, FALSE otherwise.
This function shows if the original structure is valid or not.
The parameters are as follows:
Molecule: The input molecule to be checked.
