n [r] atoms
Sets the maximum number of bonds for the specified atoms to n and changes the default bond radius for the given atom type to r.
>>conn 5 \$Csets the maximum number of bonds all C atoms can have to 5
>>conn 1.3 \$Cchanges the bonding radius for C atoms to 1.3 (the floating point is used to distinguish between n and r in this case).
>>conn 5 1.3 \$Ccombines the two commands above
