Graphic Design Guidelines

Edit

Introduction

nf-core has a variety of recognisable images and other graphic designs for the community project. To help facilitate the identification of nf-core pipelines and related material, we provide here a variety of files that can be used for all nf-core-related content, such as pipeline logos, presentations, or workflow diagrams.

All files are released under various forms of ‘open’ licenses, meaning you can re-use and re-model as you see fit.

Logo

All information for the nf-core logo can be seen at the nf-core/logos GitHub repository and are released under the MIT license.

Type	Logo	Links
Main nf-core logo		PNG SVG Adobe Illustrator .ai
Dark backgrounds		PNG SVG Adobe Illustrator .ai
Monochrome - dark background		PNG SVG Adobe Illustrator .ai
Square		PNG SVG Adobe Illustrator .ai

The nf-core pipelines create command will generate a logo for your pipeline automatically. However, you can also do this yourself by visiting https://nf-co.re/logo/pipelinename, where pipelinename can be anything.

Please note that nf-core is a separate entity from Nextflow. You can find information about the Nextflow trademark with associated logo files at https://github.com/nextflow-io/trademark

Font & Colours

The font used in nf-core designs is Maven Pro Bold (700), available at Google Fonts, under the Open Font License.

The nf-core green colour is as follows:

• RGB: 36,176,100
• Hex: #24B064

Workflow Schematics

It is often useful to have simplified diagrams that outline the main functionality and steps of a pipeline. This helps new users get an overview of a workflow when visiting a pipeline webpage or repository for the first time.

Most workflow diagrams are made by hand using vector image editors such as the open-source Inkscape or commercial suites such as Adobe Illustrator. Useful tools for collaborative prototyping include Google Drawings or LucidChart. All examples and components below can be opened in these editors, and various parts borrowed and/or modified as necessary.

The components are also made available on bioicons, which offers extensions for Inkscape and draw.io to directly import them there.

Examples

See below for some examples of nf-core workflow schematics that can be re-used and modified for your own pipeline.

Use draw.io

The web app draw.io helps you create, render and export different diagrams including metro-maps. For even more convenience you can use the following asset library nf-core xml item library. It contains all of the components from the cheatsheet above. To import it to draw.io use “File / Open library from / URL…” and paste:

Additionally, the components can be used via bioicons.
