[galaxy-dev] adding new tools and wrapper validation!

Hi, I am sure these questions had been asked before but could not find the right answer or did not look enough :) . I just want to add new aligner tool wrapper into local galaxy. I used the existing wrappers (i.e bwa) as template and then modified it accordingly. Here are what I did: Create an xml file and put it to "~tools/sr_mapping/mytool.xml" * Created a py file and added it to the same folder "~tools/sr_mapping/myTool.py" * Configured the tool_conf.xml file * Restarted my galaxy server However, the new tool did not show up in the GUI. Is there anything else I am missing? Is there a validation step I need to perform for both files? I appreciate your help. Regards
