Tutorial for model free SBiNLab

Background

This is a tutorial for Lau and Kaare in SBiNLab, and hopefully others.

To get inspiration of example scripts files and see how the protocol is performed, have a look here:

• nmr-relax-code/test_suite/system_tests/scripts/model_free/dauvergne_protocol.py
• nmr-relax-code/auto_analyses/dauvergne_protocol.py

model-free : Script inspiration for setup and analysis

The distribution of relax includes a folder sample_scripts/model_free which contain a folder with scripts for analysis.

It can be seen here: https://github.com/nmr-relax/relax/tree/master/sample_scripts/model_free

Here is the current list

• back_calculate.py. Back-calculate and save relaxation data starting from a saved model-free results file.
• bmrb_deposition.py Script for creating a NMR-STAR 3.1 formatted file for BMRB deposition of model-free results.
• cv.py Script for model-free analysis using cross-validation model selection.
• dasha.py Script for model-free analysis using the program Dasha.
• dauvergne_protocol.py Script for black-box model-free analysis.
• diff_min.py Demonstration script for diffusion tensor optimisation in a model-free analysis.]
• final_data_extraction.py Extract Data to Table
• generate_ri.py Script for back-calculating the relaxation data.
• grace_S2_vs_te.py Script for creating a grace plot of the simulated order parameters vs. simulated correlation times.
• grace_ri_data_correlation.py Script for creating correlations plots of experimental verses back calculated relaxation data.
• map.py Script for mapping the model-free space for OpenDX visualisation.
• mf_multimodel.py This script performs a model-free analysis for the models 'm0' to 'm9' (or 'tm0' to 'tm9').
• modsel.py Script for model-free model selection.
• molmol_plot.py Script for generating Molmol macros for highlighting model-free motions
• palmer.py Script for model-free analysis using Art Palmer's program 'Modelfree4'
• remap.py Script for mapping the model-free space.
• single_model.py This script performs a model-free analysis for the single model 'm4'.
• table_csv.py Script for converting the model-free results into a CSV table.
• table_latex.py Script for converting the model-free results into a LaTeX table.

Other script inspiration for checking

The distribution of relax includes a folder sample_scripts/ which contain a folder with scripts for analysis.

It can be seen here: https://github.com/nmr-relax/relax/tree/master/sample_scripts R1 / R2 Calculation

• relax_fit.py Script for relaxation curve fitting.
• relax_curve_diff.py Script for creating a Grace plot of peak intensity differences.

The resultant plot is useful for finding bad points or bad spectra when fitting exponential curves determine the R1 and R2 relaxation rates. If the averages deviate systematically from zero, bias in the spectra or fitting will be clearly revealed. To use this script, R1 or R2 exponential curve fitting must have previously have been carried out the program state saved to the file 'rx.save' (either with or without the .gz or .bz2 ). The file name of the saved state can be changed at the top of this script.

NOE calculation

• noe.py Script for calculating NOEs.

Test data

• jw_mapping.py Script for reduced spectral density mapping.
• consistency_tests.py Script for consistency testing.

Severe artifacts can be introduced if model-free analysis is performed from inconsistent multiple magnetic field datasets. The use of simple tests as validation tools for the consistency assessment can help avoid such problems in order to extract more reliable information from spin relaxation experiments. In particular, these tests are useful for detecting inconsistencies arising from R2 data. Since such inconsistencies can yield artifactual Rex parameters within model-free analysis, these tests should be use routinely prior to any analysis such as model-free calculations. This script will allow one to calculate values for the three consistency tests J(0), F_eta and F_R2. Once this is done, qualitative analysis can be performed by comparing values obtained at different magnetic fields. Correlation plots and histograms are useful tools for such comparison, such as presented in Morin & Gagne (2009a) J. Biomol. NMR, 45: 361-372.

Other representations

• angles.py Script for calculating the protein NH bond vector angles with respect to the diffusion tensor.
• xh_vector_dist.py Script for creating a PDB representation of the distribution of XH bond vectors.
• diff_tensor_pdb.py Script for creating a PDB representation of the Brownian rotational diffusion tensor.

Scripts - Dont use this section

What was learned from this section, was better implemented in Scripts - Part 2. Use this section instead.

Plan of execution

To get the protocol to work, we need to

• Load a PDB structure
• Assign the "data structure" in relax through spin-assignments
• Assign necessary "information" as isotope information to each spin-assignment
• Read "R1, R2 and NOE" for different magnet field strengths
• Calculate some properties
• Check the data
• Run the protocol

To work most efficiently, it is important to perform each step 1 by 1, and closely inspect the log for any errors.

01_read_pdb.py - Test load of PDB

First we just want to test to read the PDB file.

03_save_state_inspect_GUI.py - Inspect data in GUI

The GUI can be a good place to inspect the setup and files.

See content of: 03_save_state_inspect_GUI.py

Run with

relax 03_save_state_inspect_GUI.py -t 03_save_state_inspect_GUI.log

To check in GUI

• relax -g
• File -> Open relax state
• In folder "result_03" open "result_03_ini.bz2"
• View -> Data pipe editor
• Right click on pipe, and select "Associate with a new auto-analysis"

04_run_default_with_tolerance_lim.py - Try fast run

Now we try a fast run, to see if everything is setup

See content of: 04_run_default_with_tolerance_lim.py

Before running, is worth to note, which values are NOT set to default values in the GUI.

• dAuvergne_protocol.opt_func_tol = 1e-10 # Standard: opt_func_tol = 1e-25
• dAuvergne_protocol.opt_max_iterations = int(1e5) # Standard: opt_max_iterations = int(1e7)

These 2 values is used in the minfx python package, and is an instruction to the minimiser function, to continue changing parameter values, UNTIL either the difference in chi2 values between "2 steps" is less than 1e-10, OR if the number all steps is larger than 10^5. It's an instruction not to be tooooo pedantic, here in the exploration phase. When finalising for publication, these values should be set to their standard value.

• MC_NUM = 20

Number of Monte-Carlo simulations. The protocol will find optimum parameter values in this protocol, but error estimation will not be very reliable. Standard is 500.

We use tmux to make a terminal-session, we can get back to, if our own terminal connection get closed.

• start a new session: tmux
• re-attach a detached session: tmux attach

Run with

# Make terminal-session
tmux

relax 04_run_default_with_tolerance_lim.py -t 04_run_default_with_tolerance_lim.log

You can then in another terminal follow the logfile by

less +F 04_run_default_with_tolerance_lim.log

• To return to follow mode, use keyboard: Shift+f
• To exit, use keyboard: Ctrl+c and then: q

05_run_def_MC20.py - Try normal run with MC 20

The inspection of the log of the previous run, it seems the prolate cannot converge. It jumps between 2 chi2 values.
Maybe it is because of the NOT default values of optimization, to let us set it back to default.

We have 4 CPU on our lab computers.
So let us assign 1 to a run normal settings, and only MC=20.

06_run_def_MC20_MAX_ITER20.py - Try normal run with MC 20 and MAX_ITER 20

It looks like the prolate has problem with converging.
So let us try a run, where a maximum of 20 rounds of convergence is accepted.

Normally between 8 to 15 multiple rounds of optimisation of the are required for the proper execution of this script.
This is can also be see here in Figure 2.

Then hopefully, relax should continue to the other models, if prolate does not converge.

We have 4 CPU on our lab computers.
Let us assign another to a run normal settings, only MC=20 and MAX_ITER=20.

After running around 12H, it is in round 14 in the prolate.

Let's us try finalize on just the current available data!

See content of: 06_check_intermediate.py

We just want to finish, and see some results. Therefore also nr. of Monte-Carlo is set to a minimum.
MC_NUM = 5

Run with. This should take 20-30 min on 1 CPU.

06_check_intermediate_iteration_chi2.py - Per iteration get chi2

Specifically, since we have problems with convergence, we would like to see the chi2 value per iteration for the different models. This is not so easy to get, and we have to make a script, that loads each result file per round folder and extract the chi2 value.

This will also get k The global number parameters and n the global number of data sets.

See content of: 06_check_intermediate_iteration_chi2.py

Run with relax

Scripts - Part 2

We now try to setup things a little more efficient.

Relax is able to read previous results file, so let us divide the task up into:

• 1: Load the data and save as state file. Inspect in GUI before running.
• 2: Run the Model 1: local_tm.
• 3: Here make 4 scripts. Each of them only depends on Model 1:
  • Model 2: sphere
  • Model 3: prolate
  • Model 4: oblate
  • Model 5: ellipsoid
• 4: Make an intermediate 'final' model script. This will automatically detect files from above.

Prepare data

We make a new folder and try again.

mkdir 20171010_model_free_2_HADDOCK
cp 20171010_model_free_HADDOCK/*.dat 20171010_model_free_2_HADDOCK
cp 20171010_model_free_HADDOCK/*.pdb 20171010_model_free_2_HADDOCK

# Get scripts
cd 20171010_model_free_2_HADDOCK
git init
git remote add origin git@github.com:tlinnet/relax_modelfree_scripts.git
git fetch
git checkout -t origin/master

And a new one, changing the NOE error

mkdir 20171010_model_free_3_HADDOCK
cp 20171010_model_free_HADDOCK/*.dat 20171010_model_free_3_HADDOCK

11_read_data_GUI_inspect.py - Read data GUI inspect

This will read the data and save as a state.

The GUI can be a good place to inspect the setup and files.

See content of: 11_read_data_GUI_inspect.py

Run with

relax 11_read_data_GUI_inspect.py -t 11_read_data_GUI_inspect.log

To check in GUI

• relax -g
• File -> Open relax state
• In folder "result_10" open "result_10_ini.bz2"
• View -> Data pipe editor
• Right click on pipe, and select "Associate with a new auto-analysis"

12_Model_1_I_local_tm.py - Only run local_tm

Now we only run Model 1.

• DIFF_MODEL = ['local_tm']
• GRID_INC = 11 # This is the standard
• MC_NUM = 0 # This has no influence in Model 1-5
• MAX_ITER = 20 # Stop if it has not converged in 20 rounds

Normally between 8 to 15 multiple rounds of optimisation of the are required for the proper execution of this script.
This is can also be see here in Figure 2.

Relax should stop calculation, if a model does not converge.

See content of: 12_Model_1_I_local_tm.py

We use tmux to make a terminal-session, we can get back to, if our own terminal connection get closed.

Run with

# Make terminal-session
tmux new -s m1

relax 12_Model_1_I_local_tm.py -t 12_Model_1_I_local_tm.log

# or
tmux new -s m1_multi
mpirun -np 16 relax --multi='mpi4py' 12_Model_1_I_local_tm.py -t 12_Model_1_I_local_tm.log

You can then in another terminal follow the logfile by

less +F 12_Model_I_local_tm.log

• To scroll up and down, use keyboard: Ctrl+c
• To return to follow mode, use keyboard: Shift+f
• To exit, use keyboard: Ctrl+c and then: q

13_Model_2-5 - Run Model 2 to 5

When Model 1 is completed, then make 4 terminal windows and run them at the same time.

tmux new -s m2
relax 13_Model_2_II_sphere.py -t 13_Model_2_II_sphere.log
# When relax is running, push: Ctrl+b and then d, to disconnect without exit

tmux new -s m3
relax 13_Model_3_III_prolate.py -t 13_Model_3_III_prolate.log
# When relax is running, push: Ctrl+b and then d, to disconnect without exit

tmux new -s m4
relax 13_Model_4_IV_oblate.py -t 13_Model_4_IV_oblate.log
# When relax is running, push: Ctrl+b and then d, to disconnect without exit

tmux new -s m5
relax 13_Model_5_V_ellipsoid.py -t 13_Model_5_V_ellipsoid.log
# When relax is running, push: Ctrl+b and then d, to disconnect without exit

To join session

# List
tmux list-s

# Join either
tmux a -t m1
tmux a -t m2
tmux a -t m3
tmux a -t m4
tmux a -t m5

14_intermediate_final.py - Inspection during model optimization

During running of model 2-5, the current results can be inspected with this nifty scripts.

The script will ask for input of MC numbers. So just run it.

tmux new -s final
relax 14_intermediate_final.py -t 14_intermediate_final.py

This does:

• Option: Collect current best result from Model 2-5, and make MC simulations, and finalize to get current results files
  • Make analysis script for palmer Modelfree4
  • Get more spin information
• Make a pymol file, that collects all of relax pymol command files into 1 pymol session
• Option: Collect all chi2 and number of params k, for each iteration per model
  • Make a python plot file for plotting this results

To run on Haddock

Have a look here, how to get standalone python Anaconda linux. Also have a look here OpenMPI.

# SSH in
ssh haddock

# Test with shell
mpirun -np 6 echo "hello world"

# Test with python
mpirun -np 6 python -m mpi4py helloworld

# Test with relax
mpirun -np 6 relax --multi='mpi4py'
# Look for: Processor fabric:  MPI 2.2 running via mpi4py with 5 slave processors & 1 master.  Using MPICH2 1.4.1.

Now we run 04_run_default_with_tolerance_lim.py with more power!
We use tmux to make a terminal-session, we can get back to, if our own terminal connection get closed.

• start a new session: tmux
• re-attach a detached session: tmux attach

# Make terminal-session
tmux

# Start relax
mpirun -np 20 relax --multi='mpi4py' 04_run_default_with_tolerance_lim.py -t 04_run_default_with_tolerance_lim.log

Useful commands to log file

While the analysis is running, these commands could be used to check the logfile for errors

### Check convergence 
# For chi2
cat 04_run_default_with_tolerance_lim.log | grep -A 10 "Chi-squared test:"

# For other tests
cat 04_run_default_with_tolerance_lim.log | grep -A 10 "Identical "
cat 04_run_default_with_tolerance_lim.log | grep -A 10 "Identical model-free models test:"
cat 04_run_default_with_tolerance_lim.log | grep -A 10 "Identical diffusion tensor parameter test:"
cat 04_run_default_with_tolerance_lim.log | grep -A 10 "Identical model-free parameter test:"

# To look for not converged errors
# For chi2
cat 04_run_default_with_tolerance_lim.log | grep -B 7 "The chi-squared value has not converged."

# For other tests
cat 04_run_default_with_tolerance_lim.log | grep -B 7 " have not converged."
cat 04_run_default_with_tolerance_lim.log | grep -B 7 "The model-free models have not converged."
cat 04_run_default_with_tolerance_lim.log | grep -B 7 "The diffusion parameters have not converged."
cat 04_run_default_with_tolerance_lim.log | grep -B 7 "The model-free parameters have not converged."

You can then inspect the logfile by less: 10-tips for less

less 04_run_default_with_tolerance_lim.log

To find pattern: We have to escape with \ for special character like: ()[] etc.

# Search forward
/Value \(iter 14\)
/The chi-squared value has not converged

n or N – for next match in forward / previous match in backward

• To return to follow mode, use keyboard: Shift+f
• To exit, use keyboard: Ctrl+c and then: q

About the protocol

Model I - 'local_tm'
This will optimise the diffusion model whereby all spin of the molecule have a local tm value, i.e. there is no global diffusion tensor. This model needs to be optimised prior to optimising any of the other diffusion models. Each spin is fitted to the multiple model-free models separately, where the parameter tm is included in each model.

Model II - 'sphere'
This will optimise the isotropic diffusion model. Multiple steps are required, an initial optimisation of the diffusion tensor, followed by a repetitive optimisation until convergence of the diffusion tensor. In the relax script UI each of these steps requires this script to be rerun, unless the conv_loop flag is True. In the GUI (graphical user interface), the procedure is repeated automatically until convergence. For the initial optimisation, which will be placed in the directory './sphere/init/', the following steps are used:

• The model-free models and parameter values for each spin are set to those of diffusion model MI.
• The local tm parameter is removed from the models.
• The model-free parameters are fixed and a global spherical diffusion tensor is minimised
• For the repetitive optimisation, each minimisation is named from 'round_1' onwards. The initial 'round_1' optimisation will extract the diffusion tensor from the results file in './sphere/init/', and the results will be placed in the directory './sphere/round_1/'. Each successive round will take the diffusion tensor from the previous round. The following steps are used:
  • The global diffusion tensor is fixed and the multiple model-free models are fitted to each spin.
  • AIC model selection is used to select the models for each spin.
  • All model-free and diffusion parameters are allowed to vary and a global optimisation of all parameters is carried out.

Model III - 'prolate'
The methods used are identical to those of diffusion model MII, except that an axially symmetric diffusion tensor with Da >= 0 is used. The base directory containing all the results is './prolate/'.

Model IV -'oblate'
The methods used are identical to those of diffusion model MII, except that an axially symmetric diffusion tensor with Da <= 0 is used. The base directory containing all the results is './oblate/'.

Model V - 'ellipsoid'
The methods used are identical to those of diffusion model MII, except that a fully anisotropic diffusion tensor is used (also known as rhombic or asymmetric diffusion). The base directory is './ellipsoid/'

'final'
Once all the diffusion models have converged, the final run can be executed. This is done by setting the variable diff_model to 'final'. This consists of two steps, diffusion tensor model selection, and Monte Carlo simulations. Firstly AIC model selection is used to select between the diffusion tensor models. Monte Carlo simulations are then run solely on this selected diffusion model. Minimisation of the model is bypassed as it is assumed that the model is already fully optimised (if this is not the case the final run is not yet appropriate). The final black-box model-free results will be placed in the file 'final/results'.
