It is certainly the same for other plugins, and this is the only places where environ is fed to CommandLine in whole nipype.\r\n\r\nAny idea how to fix this?\r\nThanks"},"comment":{"url":"https://api.github.com/repos/nipy/nipype/issues/comments/247430182","html_url":"https://github.com/nipy/nipype/issues/1621#issuecomment-247430182","issue_url":"https://api.github.com/repos/nipy/nipype/issues/1621","id":247430182,"user":{"login":"bpinsard","id":1155388,"avatar_url":"https://avatars.githubusercontent.com/u/1155388?v=3","gravatar_id":"","url":"https://api.github.com/users/bpinsard","html_url":"https://github.com/bpinsard","followers_url":"https://api.github.com/users/bpinsard/followers","following_url":"https://api.github.com/users/bpinsard/following{/other_user}","gists_url":"https://api.github.com/users/bpinsard/gists{/gist_id}","starred_url":"https://api.github.com/users/bpinsard/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/bpinsard/subscriptions","organizations_url":"https://api.github.com/users/bpinsard/orgs","repos_url":"https://api.github.com/users/bpinsard/repos","events_url":"https://api.github.com/users/bpinsard/events{/privacy}","received_events_url":"https://api.github.com/users/bpinsard/received_events","type":"User","site_admin":false},"created_at":"2016-09-15T19:39:46Z","updated_at":"2016-09-15T19:39:46Z","body":"the above PR fixes the bug..."}}
