starburst dendrimers coordinates



 Hi!
 Before I rediscover the wheel I would like to know if anyone is aware of
 a program to generate coordinates for a starburst dendrimer given
 its core and unit fragments. Alternatively, is there a repository of
 some of these coordinates, similar to those for C60?
 Thanks?
