Lately I am trying to calculate the principle components of a set of data. I successfully compiled your code (latest version), and I ran with the command:\r\n\r\n$./fastpca --file test.txt --nthreads 8 --val eigenval.out --vec eigenvec.out\r\n\r\nThe test.txt file is very simple:\r\n[test.txt](https://github.com/lettis/FastPCA/files/117874/test.txt)\r\n\r\nHowever, I ran into the problem \"Segmentation fault\". Do you know what is going on here ?\r\n\r\nThanks a million !\r\n\r\nBest,\r\nJunteng\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/lettis/FastPCA/issues/comments/179966086","html_url":"https://github.com/lettis/FastPCA/issues/1#issuecomment-179966086","issue_url":"https://api.github.com/repos/lettis/FastPCA/issues/1","id":179966086,"user":{"login":"lettis","id":1015202,"avatar_url":"https://avatars.githubusercontent.com/u/1015202?v=3","gravatar_id":"","url":"https://api.github.com/users/lettis","html_url":"https://github.com/lettis","followers_url":"https://api.github.com/users/lettis/followers","following_url":"https://api.github.com/users/lettis/following{/other_user}","gists_url":"https://api.github.com/users/lettis/gists{/gist_id}","starred_url":"https://api.github.com/users/lettis/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/lettis/subscriptions","organizations_url":"https://api.github.com/users/lettis/orgs","repos_url":"https://api.github.com/users/lettis/repos","events_url":"https://api.github.com/users/lettis/events{/privacy}","received_events_url":"https://api.github.com/users/lettis/received_events","type":"User","site_admin":false},"created_at":"2016-02-04T17:54:39Z","updated_at":"2016-02-04T17:54:39Z","body":"Dear Junteng,\r\nthank you for your feedback.\r\nSome days ago I changed the menu structure of the code, which introduced the bug.\r\nThis reminds me that I should get some unit cases written...\r\nI tested the updated code with your example, it now produces the expected results.\r\n\r\nCheers,\r\n  Florian"}}
