We are going to use a prebuilt virtual machine image for this session.

From the given USB stick, please:

Galaxy’s frontend

JavaScript sources and CSS sources are in the $GALAXY_ROOT/client folder.

Whenever you make changes there, you will need to re-build Galaxy’s frontend with:

$ make client

This requires Node.

Translation and localisation 1/2

The language for labels used in the JS source code is English, but can be wrapped in l() which makes it translatable.

_l( 'Help' )

"Analyze Data" :

Translation and localisation 2/2

When a user’s browser locale or language is set to a known translation, it will be used instead of the default. If a translation is not available for a string, it will appear in English.

How to modify the menu

Open the client/galaxy/scripts/layout/menu.js

var helpTab = {
          id              : 'help',
          title           : _l('Help'),
          tooltip         : _l('Support, contact, and community'),
          menu            : [{
                  title   : _l('Support'),
                  url     : options.support_url,
                  target  : '_blank'
                  title   : _l('Search'),
                  url     : options.search_url,
                  target  : '_blank'

Configuration tweaks

Plenty of customisation can be achieved using settings in the main configuration file galaxy.yml

Tool Panel configuration

Tool panel labels

You can add <tool labels="updated" /> to achieve:

tool panel labels

Tool Panel search configuration 1/2

The tool panel search uses a pre-built index that is compiled during Galaxy boot. You can tweak tool panel search by configuring boosts in galaxy.yml.

tool_name_boost: 9
tool_section_boost: 3
tool_description_boost: 2
tool_label_boost: 1
tool_stub_boost: 5
tool_help_boost: 0.5

You can also manipulate the number of tools returned for any query by changing the tool_search_limit. This will display more or fewer tools for any given query.

Tool Panel search configuration 2/2

# Enable/ disable Ngram-search for tools. It makes tool
# search results tolerant for spelling mistakes in the query
# by dividing the query into multiple ngrams and search for
# each ngram
tool_enable_ngram_search: true

# Set minimum and maximum sizes of ngrams
tool_ngram_minsize: 3
tool_ngram_maxsize: 5

Log level configuration

# Verbosity of console log messages.
log_level: DEBUG

These are python logging levels.

## Toolbox filtering

– ToolBox filtering

Modules from lib/galaxy/tools/toolbox/filters/ can be specified in

the following lines. tool_* filters will be applied for all users

and can not be changed by them. user_tool_* filters will be shown

under user preferences and can be toggled on and off at

runtime. Example shown below are not real defaults (no custom

filters are applied by default), but can be enabled by renaming the in the filters directory to

#tool_filters = #tool_label_filters = #tool_section_filters = #user_tool_filters: examples:restrict_upload_to_admins, examples:restrict_encode #user_tool_section_filters: examples:restrict_text #user_tool_label_filters: examples:restrict_upload_to_admins, examples:restrict_encode

The base modules that are searched for modules as described above

can be modified and modules external to Galaxy can be searched by

modifying the following option.

#toolbox_filter_base_modules:, ```


Used to control user disk usage.

To turn on the use of quotas: In galaxy.yml:


Default for user class:

or associated with Groups or Users

Exercise: Creating Quotas
