Hi Edward and thanks for your message. Yes, I am looking forward to mastering your software. I hope I do not bug you with too many questions, and that the learning curve will be steep. See below:
Welcome to the relax mailing lists! I have just tried out your PDB file attached to the bug report. I launched the relax in GUI mode and performed the following steps: - Selected a model-free analysis from the new analysis wizard (this is the special dauvergne_protocol auto-analysis which is worth reading about to understand what is happening). - Clicked on the 'Spin editor' button. - Clicked on the 'Load spins' button in the spin editor window. - Selected the option 'From a new PDB file' in the spin loading wizard. - Loaded your PDB file. - Set the spin ID to '@N' and '@H' to load the 15N and 1H spins of the backbone. '@NE1' and '@HE1' spins should probably be loaded as well. - Click on 'Finish'.
I think I did all the steps that you describe here below yesterday, except fot the only fact that I changed the string about the molecule name, which seems unlikely to be the cause of my failure. Now, and I did it several times, I do not have any problems in reading the spins for the PDB file. OK then!
I can now see the 15N and 1H spins for two molecules. To perform a model-free analysis, I could simply delete one of the two molecules and continue.
question arises: the protein is a homodimer in solution, and I do not think I should delete any spin nor molecule. Am I correct? If I do, I start from a wrong geometric model, no? Stefano
