Hi, I am currently writing a script for random deletions in a molecule and I have encountered a problem with deleting any fragments which appear in the structure.  My molecule is an organic polymer and I am deleting random bonds in the polymer.  I tried to use the molecule function in order to select the number of molecules in the unitcell in order to detect any fragments in the structure.  However for some reason, the print function is returning a molecule count of 18 for a 3x3x1 unitcell when only one molecule is present. I tried it on a 5x5x5 cell and a count of 250 was returned. 

This leads to my question. What does the function "molecule" signify in materials studio?
