I am running it on a dataset that has several hundreds nodes, but it doesn't work. I found that command line TETRAD doesn't work if the dataset has more than 100 nodes (predictors and target), which means that it works for a dataset with only up to 100 nodes.   The number of cases doesn't matter; it works well for a dataset with > 1000 cases, once the number of nodes is less than 100. However, it seems that it doesn't work if the number of nodes exceeds 100. Innumerable error messages were made and it flew over the windows command.  I got a screenshot of error messages and attached here. Command line TETRAD has a limitation to be run on a dataset with less than 100 nodes or something?\r\n\r\nSanghoon \r\n\r\n![errormessage_morethan100nodes](https://cloud.githubusercontent.com/assets/15758093/12010940/2434a472-ac89-11e5-8b6b-108deaf864f3.png)\r\n"},"comment":{"url":"https://api.github.com/repos/cmu-phil/tetrad/issues/comments/167607879","html_url":"https://github.com/cmu-phil/tetrad/issues/122#issuecomment-167607879","issue_url":"https://api.github.com/repos/cmu-phil/tetrad/issues/122","id":167607879,"user":{"login":"biotech25","id":15758093,"avatar_url":"https://avatars.githubusercontent.com/u/15758093?v=3","gravatar_id":"","url":"https://api.github.com/users/biotech25","html_url":"https://github.com/biotech25","followers_url":"https://api.github.com/users/biotech25/followers","following_url":"https://api.github.com/users/biotech25/following{/other_user}","gists_url":"https://api.github.com/users/biotech25/gists{/gist_id}","starred_url":"https://api.github.com/users/biotech25/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/biotech25/subscriptions","organizations_url":"https://api.github.com/users/biotech25/orgs","repos_url":"https://api.github.com/users/biotech25/repos","events_url":"https://api.github.com/users/biotech25/events{/privacy}","received_events_url":"https://api.github.com/users/biotech25/received_events","type":"User","site_admin":false},"created_at":"2015-12-28T17:29:51Z","updated_at":"2015-12-28T17:29:51Z","body":"I reboot computer and re-ran, or tried in on Mac or another Windows server.
