Dear All, how to built a new ligand and refine the pdb, since the refmac is failed with the following message *Refmac died because it encountered a ligand not present in the monomer libraries it has read (i.e. the default CCP4 libraries plus any library you provided through the GUI). To continue, you have a number of options.*
I would be very much grateful, if you could send me the protocol links to built and add a new ligand in the library. Thank you Regards Yuvaraj
