SMARTS database: One of the great strengths of the DAYLIGHT system has always been the ability to describe chemical concepts. Remember GCL!!!
Whilst SMARTS is powerful, it is not a language which is easily remembered by occasional users. What has been put together has been a database which allows SMARTS to be stored and retrieved in a sensible fashion. The trees are rooted on the name for the SMARTS, a suggested convention is that the first character is uppercase and the rest lower case, like monomers. So, if we have a basic nitrogen, N_basic would be a suitable, though arbitrary name.
The tree contains data items for the SMARTS itself, and the English language description of what the SMARTS means. For an international company like ours there is no reason why the description could not be in Italian, French or Spanish. Finally the originator of the SMARTS is added.
