new tutorial

Many analyses in Galaxy require small data manipulations in between tools as a sort of “glue” between analysis steps. For example, you may need to change the file format, re-order columns in a table, replace certain values, or perform some filtering operation, before you can proceed to the next step of your analysis. Galaxy offers a wide range of tools that can perform such generic data manipulation tasks, and mastering these types of operations in Galaxy can help you streamline your analysis and get the most out of Galaxy.

new feature

Did you ever start teaching a GTN tutorial, only to realise something changed recently? Oh no! A while ago the GTN created an Archive to address just this concern. On every tag, we’d build a copy of the website which we would place online and never touch again. This way we’d have permanent online copies so that if someone needed to go back to an older version of the GTN, they could.

new tutorial español

¡El primer tutorial en español ya está disponible! Galaxy siempre ha tenido tutoriales traducidos automáticamente mediante Google-Translate, ahora nos estamos embarcando en un nuevo proyecto para estudiar la experiencia de aprendizaje con tutoriales en bioinformática traducidos por humanos. Nuestro objetivo es crear un paquete de tutoriales para el análisis de datos single-cell (célula única) en primera instancia, con el fin de estudiar su uso y utilidad en un taller para hablantes nativos de español. Agradecemos enormemente a las nuevas participantes @gtn:pclo y @gtn:ales-ibt (EMBL-EBI) así como a las miembros existentes de GTN @gtn:beatrizserrano (University of Freiburg), @gtn:shiltemann & @gtn:hexylena (Erasmus-MC), por su arduo trabajo en este proyecto de traducción y mantenimiento y, por supuesto, a @gtn:nomadscientist (The Open University/EBI) como líder de proyecto.

gtn infrastructure contributors instructors new feature

Snippets have received an major overhaul! Snippets/FAQs are small reusable bits of training, often answering a single question. In addition to the general Galaxy snippets, we now also support topic-level and tutorial-level FAQs. This will allow contributors to add common questions and answers to their tutorials, which not only can be included in the tutorial text itself, but are also used to autogenerate an FAQ page for the tutorial or topic listing all common questions (and answers).This will be useful both to participants following tutorials via self-study, and also to instructors preparing for a training event.
