merge multiple VCF files - variant analysis and sample organization

Thank you for your answer!
I followed the tutorial you suggested and also the “Identification of somatic and germline variants from tumor and normal sample pairs” tutorial (https://galaxyproject.github.io/training-material/topics/variant-analysis/tutorials/somatic-variants/tutorial.html#variant-annotation-and-reporting), successfully.

1)I am interested in learning more about the GEMINI annotate and query and Join files to customize my analysis. I am trying to download the gnomad database but I am failing in downloading the dataset. It cannot recognize the vcf.bgz.tbi extension, I think.
Would you suggest how can I download this dataset?

2)during the tutorials I realized that the some commands are on usegalaxy.org and others on galaxy Europe. Is there any way to share the history between the two websites?

  1. Lastly for annotate query, learning SQL language is always needed? Or I can use other command like filter and sort? (to remove frequent variant for example)

Thanks in advance for your help.
