[galaxy-user] Installing tool in galaxy on cloud

Hi All, I want to use Tophat2 on amazon cloud. I could not find it in the regular tools unlike the public server. Am I using the right version? I tried installing it through admin on cloud .Though I was able to make myself admin through cloudman instance , I could not see any admin panel on Galaxy main page. What am I doing wrong?Any help is appreciated. Thanks. Shivani
