These tutorials takes place virtually on the 11th and 13th of September of 2021 (14-18:30), as a part of the EMBO workshop for Image processing in cryoEM
- 1 Tutorials
- 2 Contents
- 2.1 Alignment of tilt series
- 2.2 Models
- 2.3 Template matching
- 2.4 Subtomogram averaging
- 2.5 High resolution pipelines
Please refer to your course material to access your two sets of credentials.
- A set of credentials to enter Guacamole (the platform for connecting via browser). These are common to all participants.
- A set of course credentials to enter the actual machines where the course will be done: the EMBO21 UserID. These are unique to each participant.
Connecting to guacamole
- Go to the direction
in your browser. At this stage you should maximise your browser, otherwise you will have visualisation problems when opening Dynamo.
- Enter your Guacamole credentials.
Connecting to your machine
Now you need to select a machine. Please then click on +em and then +Servers - Public and select server Zeus-0-14.
When you select the machine, you will prompted to use your EMBO21 UserID
This should access your virtual Linux XFCe desktop, which should look like this in your browser
If you open a terminal (with the terminal icon) you can test by typing
that you are in the correct path, which should be:
where XX stands for your actual workshop participant number.
First you load the standalone version of Dynamo:
module load dynamo/v1.1.524
and then it will be available
Dynamic of the course
The course is divided on different modules, described in the time schedule below. Each module is structured in three stages:
- all students are connected to the main room; goals of the module will be explained by an instructor.
- Individual work
- students go the breakout rooms they have been assigned and perform the tasks of the walkthrough in the tutorial.
- an instructor will be assigned to each breakout room.
- Common discussion
- on the last 5 minutes of the module, we come back to the general breakout room for discussion of problems found.
Each module has one or several walkthroughs. The data of the walkthroughs is sometimes synthetic and created on the fly, and sometimes a data set is necessary. In such cases, the text of walkthrough will point to an on-line location where the data can be downloaded.
During this course, the data will be also available in the filesystem, you will not need to download it.
The general repository for the data is:
This time schedule is tentative
Day 1: Tomography
|14:30||Tilt series alignment: manually|
|15:00||Tilt series alignment: GUI|
|15:30||Tilt series alignment: command line|
|16:30||Models: catalogue system|
|17:00||Models: helical symmetry|
|17:30||Models: vesicles and surfaces|
Day 2: Subtomogram averaging
|14:30||Getting started: synthetic thermosomes|
|15:30||Advanced tutorial: FHV|
|18:00||High resolution pipelines|
Alignment of tilt series
We will align the same tilt series tilt series with three different approaches.
The data is available at:
Manual alignment of tilt series
We will click manually on the gold beads of our test tilt series Walkthrough on manual marker clicking
Automated alignment of tilt series through the GUI
Automated alignment of tilt series through the command line
Vesicle and surface models
tutorial on membrane modeling with dmslice
Reusing model workflows ( walkthrough)
walkthrough for automated identification of proteosomes on a real tomogram through template matching. (~1 hour)
The data is available at:
- 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.
Advanced starters guide
Complete the advanced starters guide (~2 hours) The data can be found in
To use chimera path you need in the tutorial is
Tutorial from densely packed spherical geometry (~1 hour). The data is available at:
High resolution pipelines
Exercise to train a realistic case including all processing steps from catalogue creation to final structure using a reduced dataset. Start with the exercise and refer to the complete walkthrough for guidance or the solution.
Alister: Not a tutorial per se: this is a presentation on a set of tools to interconnect Dynamo, M and other software.
A set of tools have been developed which provide a means to use the geometrical tools and alignment projects from Dynamo with data preprocessed in Warp. These tools mean that particle picking and alignment can be performed in Dynamo prior to multi-particle refinement in M.
