Dear Admin, Since the upgrade, I lost the samtools that I installed myself. Although it is still in the tool_conf.xml, it does not show up on the panel. I tried to install from toolshed, but failed. Error messages pasted below. Could someone take a look? Thanks, Rui ⇝ AttributeError: 'NoneType' object has no attribute 'strip' URL: http://128.125.28.215/admin_toolshed/prepare_for_install?tool_shed_url=ht...
