Hello @yahia.elshabrawy
Yes, Annovar
at https://usegalaxy.org is currently non-functional. The tool will likely be deprecated: Annovar -- complete fixup for Py3 on Main · Issue #284 · galaxyproject/usegalaxy-playbook · GitHub
Alternative VCF annotation tools can be found in the tool grouping “Variant Calling”. SnpEff
is one example.
GTN Tutorials may help with usage and creating a workflow. Start with those under the topic “Variant Analysis”.
Hope that helps!
