Young-Jin Which version of PHENIX are you using? If you send your files directly to me I'll determine what is happening. Nigel On 2/16/09 8:34 AM, Young-Jin Cho wrote:
Hi, my current wonderings are as below: First, how can I add H atoms into nucleotide ligands in pdb file? I did 'phenix.reduce model.pdb > model_h.pdb', but as I see it didn't add H's of sugar (1', 2', 3' 4' and 5'). Once I had this kind of problem before, I was suggested to use phenix.ready_set command but seemingly this does not work any longer with last version that I am using now. Also, is it possible to add H into phosphate group?
The second very general question is about getting over overfitting problem. My phenix runs gave me too much difference between R and Rfree about .7 w/o adding H atoms. I assume it came from water molecules because it(huge gap) just starts to happen after 1_bss stage. If anybody can suggest a good way to get over this problem, you will save my tremendous times and useless efforts.
Big thanks in advance,
Young-Jin
