Do you mean that the residue numbers were out by 7? I have considered this, but relax currently has no way of renumbering the residues in a 3D structure or renumbering the residues of the input data. So unfortunately you'll either have to use a molecular view to change your PDF file, or a script or spreadsheet to renumber your input data. > I adjusted my relax data (simply added 7 residues with no values), and ran > it again (all settings the same as before, everything automatic). I don't think that your data will match up to the correct residues.

If the 3D info and input data do not match, then the results for non-isotropic (ellipsoidal and spheroidal diffusion) will make no sense. In relax you should never need to add relaxation data for these 7 residues, as relax will handle this situation automatically. What does your input relaxation data look like?

Troubleshooting model-free analysis
Hi, I had some general questions regarding model-free analysis that came up as I was running it. About 2 months ago, I ran model-free on a 126 residue protein. The pdb file I used for the protein had an extra 7 residue modifier at one of the terminals, which made it 133 residues; thus, my data did not match the pdf file. That run took a little over a week, with the sphere model running about 2 models, along with every other model being about 2. The data for this run I obtained was unusable (values as small as 5x10^-30 for S^2). I attributed this to the fact that my pdf files sequence did not align with my data. I adjusted my relax data (simply added 7 residues with no values), and ran it again (all settings the same as before, everything automatic). This time it has taken almost a month, with the sphere model on its 20th run. I saw in a previous email that the max is 30 iterations. Is it normal to hit the max? Does this mean my data is bad if it requires the max 30 iterations? Also, why is it running up to 20 now? The 7 residues I added didn't have data, so it doesn't run models for them. I assumed there would be a difference in time since the data is now attributed to different spins, but not this much of a difference.

Hi Rakesh (or Akshay?), Sorry for the late reply, I have been quite busy over the last two months and have been unable to reply to any messages. For this error, which version of relax are you using? And which operating system are you running on? What do you see when you run: $ relax -i --tee log This error is quite strange, as the file that cannot be imported should exist on the system: [edward@localhost relax-trunk]$ ls specific_analyses/noe/api.py specific_analyses/noe/api.py Can you run the test suite? The following should give zero errors: $ relax --test-suite --tee tests.log From the error itself, this simply means that the file specific_analyses/noe/api.py is missing. Are you sure your downloaded relax distribution file is not corrupt?

Re: Troubleshooting model-free analysis
Hi Sam, Welcome to the relax mailing lists. Sorry for the late reply, I've been quite busy for the last two months. Please see below: On 2 July 2016 at 02:41, Mahdi, Samwrote: > I had 2 questions regarding the relax model-free analysis. > 1: When uploading a pdb file for the spin system, is there a certain way to > have some residues spins ignored? I guess you mean reading the spin system from a PDB file. You can do this when running the structure.load_spins user function via the spin_id parameter: http://www.nmr-relax.com/manual/structure_load_spins.html Or you can do this afterwards, either using the deselect.spin or spin.delete user functions: http://www.nmr-relax.com/manual/deselect_spin.html http://www.nmr-relax.com/manual/spin_delete.html > i.e. give it a certain range.

Is there a > way I can get the relax program to ignore the first 7 residues? If this is a model-free analysis, the residues without data will be automatically deselected prior to optimisation (you'll see this in the logs). > I tried > typing in the range I wanted (residue 8 to residue 133 inputed as [8-133]) > in the molecule number to read option, but when I did that, it gave me this > error RelaxError: No PDB file has been loaded.

Ah, I think you might be confusing the loading of a structural file and the creation of NMR-active spin systems. All atoms of the structural file will be loaded into relax, but none of these atoms will be set a spin systems. You then have to use the structure.load_spins user function to pick our the NH atoms pairs of interest. > 2: The relaxation data I have is for the backbone (NH), thus the values I > have for the backbone are for that bond.

Note that almost no one collects this data as the proton spin cannot be considered as isolated. Therefore the normal assumptions for a model-free analysis of an isolated two spin system do no hold. E.g. spin diffusion is an important effect in protons. This is also why carbon relaxation and model-free analyses are only performed at natural abundance, to ensure that the system is isolated. > When I upload the relaxation data with the Nitrogen @N spin > id string it works fine, each residue has the proper value.

Do you see this error when you run the test suite? To me this looks like a faulty installation of wxPython. These errors and the files listed have nothing to do with relax. What is your output when you run: $ relax -i Can you run the wxPython demo or the wxPython tests to make sure this is set up correctly?
