Hello, While trying to run PTATO 1.3.3 I had an issue with pulling the SnpSift container: https://github.com/ToolsVanBox/PTATO/blob/eafc29c4d887b4ba4795cb9cbff401e9bc621ef5/NextflowModules/SnpSift/4.3.1t--1/SnpSift.nf#L4 Apparently, it is not available anymore, and pulling the singularity image from another source is required.
