Hi Edward,
Just wanted to update you on the status of my runs. I had 2 potential dimer
structures. I ran Chain A and B for one of them, and Chain B for the other.
All the results were all very similar. There was missing data though
throughout (i.e. I had data for some residues for Chain A that

Hi Edward,
Oh ok. Thank you for your help, I was able to resolve the problems I had
with both proteins, and now they are both running. Since there is symmetry
within the dimer, both chain A and chain B will give me the same S^2
results correct?
Sincerely,

Hi Edward,
So when I ran it as read_mol=0, it gave me the same error. But it worked
once I changed it to read_mol=1. I thought mol=0 was for set A and mol=1
was for set B?

Hi Edward,
The protein itself is a monomer/dimer mix, normally it is a monomer;
however, the concentrations at which we observe it at (NMR concentrations
are around 1mM, the protein forms a dimer (primarily). Using titration
experiments we have found what looks to be an interface (using CSP), and

Sorry, I just want to make sure I fully understand this so I can explain it
to my PI:
So if there is symmetry, I can upload the same pdb file with the dimer (set
A and B) but tell it to read only one set. Since S^2 isn't effected too
much versus a dimer versus a monomer, the only thing that is

Hi Edward,
I'm a bit confused to that. If the protein is a dimer, and the tumbling
decreases, will that not results in altered relaxation data? Won't the
relaxation data average be higher, since it is relaxing slower due to its
increased size (tumbler slower in solution=slower relaxation back to
Hi Gary,
There is only a monomer version of it on pdb, so if you mean it in that
sense, yes. I obtained results from it; however the S^2 were very high, but
I attributed this to having data for a dimer, but using a monomer pdb file.
If you mean have I tried to just delete set B from the pdb file
Hi Sam
have you tried with only one set of coordinates (i presume these are both homo
dimers with some form of symetry plane or axis?
