I have two related questions about ghemical and it's conformational search tools. 1) After the conformers are generated in a random or systemic search, is any sort of analysis applied to eliminate ones that are duplicates of other conformers? Failing this, is it possible to generate a simulated annealing process in the molecular dynamics code? 2) Is there a way to generate an output file of the first n conformers in sdf or mol format, or as a set of files in some other format? Thanks.
