[galaxy-dev] install ProtK problems

Hi, I am currently trying to use ProtK on our Galaxy installation. I have finally installed successfully ProtK on our sever by: rvm install 1.9.3 --with-gcc=clang rvm use 1.9.3 gem install protk So, I can see all the *.rb file in the bin folder (/home/base/.rvm/gems/gems/protk-1.2.5/bin/). We also have installed TPP on our sever (/g/software/src/TPP/bin/, for example). But, when i try to run tandem_search.rb on galaxy, it shows ""Could not find X!Tandem executable" (ArgumentError)" How do I let ProtK know where i installed TPP? I have spent incredible time on this to try to make it work. Any idea or suggestions are very appreciated. Thank you very much. Best Regards, Shu-Yi
