Hi. I used the full_analysis.py script for testing and evaluating relax in comparison with published data.
The system was calcium-loaded Calbindin D9k, with R1 & NOE at 600 MHz and R2, R1 & NOE at 500 MHz. The relaxation data is of very high quality. The model selection was done using home-written software, so no ordinary model selection à Modelfree. After running full_analysis.py (removing excess models), model selection gives me local_tm as the best model for the diffusion tensor. Previous calculations (both 15N and 13C relaxation data) indicates that the diffusion tensor is to a good approximation, isotropic (only a very slight anistropy). Looking at the local_tm values for the secondary structure, most of them have a local_tm which is similar to the isotropic tensor. Is the local_tm model always correct? For a well folded protein, one would expect that the local_tm model should be invalid?
