Dear all, Until recently I'd not needed to define new datatypes while developing tools for Galaxy - instead using (and sometimes modifying) existing datatypes in situ. I have been manually 'installing' my in-development tools by added their XML files to tool_conf.xml - and this has worked fine to date. However, I would now like to experiment with defining or modifying datatypes which would eventually be defined via a datatypes_conf.xml file in a ToolShed entry. My impression from reading the latest wiki documentation on http://wiki.g2.bx.psu.edu/Tool%20Shed is that I will have to install my own local tool shed. Is there a simpler alternative? e.g. Can I add the new datatypes_conf.xml file(s) to a configuration entry instead? Thanks, Peter
