Useful Notes

If at any time after the course you need help with Dynamo/subtomogram averaging, don't hesitate to ask on the [forum in Google Groups]

Instructors

[| Daniel Castaño-Diez] - University of Basel

[| Alister Burt] - Institut de Biologie Structurale

Materials

Day 1

Basic principles

Guided presentation:

Working on your own:

  • Basic walkthrough: creating a catalogue, picking particles, launching a project.

The data can be found in

/g/cryocourse/data/dynamo/crop.rec 

the chimera path you need in the tutorial is

/g/easybuild/x86_64/CentOS/7/haswell/software/Chimera/1.13-foss-2017b-Python-2.7.14/bin/chimera
  • Further work:
    • tutorial on the use command line operations for general purposes.
    • tutorial on the use of the command line to manage projects.

Day 2

Geometric Modelling

Short guided presentation:

The data is available at

/g/cryocourse/data/dynamo/v17.rec

PCA Based Classification

Walkthrough on PCA through the command line

Day 3

Fiducial based alignment and reconstruction

These new features in Dynamo are at the testing stage.

Interfacing with Other Tools

Dynamo is designed to allow maximum user flexibility and to encourage users to design their own solutions to the specific problems posed by their data.

Alister recently spent some time integrating Dynamo with Warp and M to be able to take advantage of Dynamo for tilt-series alignment and particle picking and plug the results into M's multi-particle refinement Integration with Warp and M

Creation of 3D scenes

Working on your own:

Further support material.

  • Walkthrough on depiction and manipulation of triangulations (synthetic data).

Template matching

  • walkthrough for automated identification of proteosomes on a real tomogram through template matching. (~1 hour)

The data can be found in

/g/cryocourse/data/dynamo/t20s.mrc

Submitting jobs For GPU computing

The following is applicable for subtomogram averaging projects setup to be run in the "gpu_standalone" mode under computing environment.

Once your project is unfolded, you should have an executable file

wizardTestProject.exe

The EMBL-HD cluster uses slurm for job submission and resource allocation.

To run this project as a job on their computing resources, we should first set up a submission script, here is an example

#!/bin/bash
#SBATCH -N 1                        # number of nodes
#SBATCH -n 1                        # number of cores
#SBATCH -o slurm.%N.%j.out          # STDOUT
#SBATCH -e slurm.%N.%j.err          # STDERR
#SBATCH --mail-type=END,FAIL        # notifications for job done & fail
#SBATCH --mail-user=alisterburt@gmail.com # send-to address
#SBATCH -p gpu						# select gpu usage
#SBATCH --gres=gpu:1				# number of gpus (if using gpus)


module load dynamo
./wizardTestProject.exe

Save this text file in the same directory as the executable file, then submit the job using sbatch

sbatch dynamo_test_gpu.sl 

This should then confirm that the job has been submitted

Submitted batch job 65146729 

Submitting jobs for CPU computing

The following is applicable for subtomogram averaging projects setup to be run in the "standalone" mode under computing environment.

Once your project is unfolded, you should have an executable file

wizardTestProject.exe

The EMBL-HD cluster uses slurm for job submission and resource allocation.

To run this project as a job on their computing resources, we should first set up a submission script, here is an example using 6 cores on 1 node

#!/bin/bash
#SBATCH -N 1                        # number of nodes
#SBATCH -n 6                        # number of cores
#SBATCH -o slurm.%N.%j.out          # STDOUT
#SBATCH -e slurm.%N.%j.err          # STDERR
#SBATCH --mail-type=END,FAIL        # notifications for job done & fail
#SBATCH --mail-user=alisterburt@gmail.com # send-to address


module load dynamo
./wizardTestProject.exe

Save this text file in the same directory as the executable file, then submit the job using sbatch

sbatch dynamo_test_cpu.sl 

This should then confirm that the job has been submitted

Submitted batch job 65146755
