Copy the iAssembler folder to a directory in your Galaxy user account. + +2. Copy iAssembler.xml, iAssembler_wrapper.pl and increment.txt to a folder in /galaxy-dist/tools/ + +Note: increment.txt and iAssembler_wrapper.pl MUST be in the same directory. + +3. In iAssembler_wrapper.pl, modify the $iAssemblerBinPath to point to the iAssembler 1.3 directory in your +Galaxy user account and $iAssemblerToolPath to the path of the wrapper. + +By default they have already been assigned as: + +my $iAssemblerBinPath = '/labdata/nfs/galaxy/pkgs/iAssembler'; +my $iAssemblerToolPath = '/labdata/nfs/galaxy/galaxy-dist/tools/iAssembler'; + +4. Add the Galaxy tool information to tool_conf.xml in /galaxy-dist/ + +5. Restart Galaxy using + +./run.sh --stop-daemon + +and then + +./run.sh --reload --daemon \ No newline at end of file
