 I'm calculating molecular parameters with the E-Dragon plataform. For some
 analogues with para-nitro group the calculations presents error with values of
 -999 for all descriptors. Only a few molecules presents this. What's happening?
 The structures are in .sdf format and the program works well for many others
 Thanks for attention,
 Prof. Edilson Beserra>
