This page describes the contents of the practical hands-on sessions in Diamond (28th-29th November 2017).

Computers

Entering the terminal

The login and password are written in the front board.

Starting a Dynamo session

Dynamo is already preinstalled in the file system of Diamond. You can activate it through

 module load EM/dynamo 

As some visualizations are performed with Chimera you need to activate it as well

 module load chimera 

After Dynamo and Chimera have been loaded, you can start a session with:

 dynamo 
Opening the Dynamo console inside a linux shell with the command dynamo

Bringing the data to the local machine

Some tutorials during the workshop require downloading big files from the Dynamo wiki using wget. You don't need to do that, as they have been already downloaded into the location /dls/tmp/DynamoWorkshop/data, which is visible by all the computers in the workshop.

To speed the access to these data sets, it is convenient to make a local copy of them into your own machines. To do so, defore going to lunch, please launch the order:

/dls/tmp/DynamoWorkshop/data/fetchDataToLocalMachine.sh 

from a linux shell. This will copy the data into the directory ~/dynamo/data in your machine.
