This page describes the contents of the practical hands-on sessions for tomography through Dynamo at the Birkbeck College during the EMBO School for Image processing in Cryo Electron Microscopy (September 2019).
Installing Dynamo on your laptops
Workstations are provided by the organization. These instructions are intended for those students that want to install their own Dynamoversion in their laptops.
Donwload
The Dynamo versions on the three platforms can be obtained in the Downloads page. Please use the indications here to install it in your laptop.
Starting a Dynamo session
You need to run an activation shell (see below for information on how to do it on each platform) that can be used to run alignment projects or to initiate an interactive session using the Dynamo console. For this, you can just type:
dynamo
on a Dynamo-activated system shell and be patient: the first time a shell initiates a Dynamo process, it can takes several minutes. New invocations to the MCR libraries will be much faster, and commands inside the opened Dynamo session will run immediately.
Linux
On a Linux terminal, type:
source <DYNAMO_ROOT>/dynamo_activate_linux_with_shippedMRC.sh
Mac
On a Mac termina, type:
source <DYNAMO_ROOT>/dynamo_activate_mac_with_shippedMRC.sh
Windows
In a DOS terminal write:
C:\ <path to the Dynamo installation>\dynamo_activate_windows.bat
then open a Dynamo terminal by typing in the DOS
dynamo
If it doesn't work, type:
set PATH=%PATH%;%MCR_ROOT%\runtime\win64
and then again
C:\ <path to the Dynamo installation>\dynamo_activate_windows.bat
Running a Dynamo project in the standalone
When working with the standalone, it is not convenient to run projects directly pressing [Run] in the dcp GUI. It is a better approach to run the project in a different process.
- Open a new system shell (DOS shell in windows).
- Activate Dynamo in that shell. i.e.,
- Linux: source <DYNAMO_ROOT>/dynamo_activate_linux_with_shippedMRC.sh
- Do NOT start a Dynamo session, i.e., do not type dynamo in the shell.
- In the terminal, type the name of the execution script.
- Linux/Mac: ./ptest.exe
- Windows: ./ptest.bat
Program
Before the hands-on session, we will go to this presentation for a general introduction of the Dynamosoftware.
In the room
Guided presentation:
- Basic Dynamo jargon
- tutorial on basic elements: help, data and metadata formats.
- tutorial on the basic concept in Dynamo alignment: the project.
Working on your own
- Basic walkthrough: creating a catalogue, picking particles, launching a project.
- FHV tutorial on isolated membrane events (Practicals Birkbeck 2019)
- Further work:
Use of the command line
Geometric modeling
Short guided presentation:
- tutorial on membrane modeling with dmslice
- Filament models with dtmslice
- Reusing model workflows ( walkthrough)
- Further work: catalogue
Template matching
Working on your own:
- We will follow this walkthrough for automated identification of proteosomes on a real tomogram through template matching. (~1 hour)
Adaptive bandpass filtering
Working on your own:
- We will follow this walkthrough to create a small synthetic data set that illustrates the principles of adaptive bandpass filtering, a way of conducting a golden standard alignment procedure . (~40 mins)
Classification
Short guided presentation:
- PCA Basic concepts.
advanced subboxing tutorial: combining with PCA and MRA tutorial - Multirefererence Analysis
Basic concepts.
walkthrough (~10 min) - Further work
- Commandline operations with PCA
Creation of 3D scenes
Working on your own:
- Walkthrough on the FHV data set (~1hour)
Further support material.
- Walkthrough on depiction and manipulation of triangulations (synthetic data).
Additional tools
Wednesday afternoon session.
- Subboxing
- motivation slide: extraction of vertices from icosahedral viruses
- Basic subboxing (tutoriall)
- advanced subboxing tutorial: combining with MRA tutorial
- suggested data set: prd1 Capsides (in the folder of isolated particles)
- Manual alignment.
- Exercises
Data sets
The data sets will be updated here.
Instructors
- Daniel Castaño-Díez, University of Basel.
- Giulia Zanetti, Birkbeck College.
