FreeSurfer Support

Have you encountered an error while running a FreeSurfer tool? Please follow these steps to get help:

  1. Search the archives: It is highly likely that someone else has run into the same problem before you. The fastest way to get answers is therefore to search the archives of our mailing list.

  2. Ask a question: If you cannot find an answer in the archives, you can help us help you faster by following some simple guidelines on how to describe your problem. Once you collected the necessary information, please send it to the appropriate mailing list:

    1. FreeSurfer mailing list (<freesurfer AT nmr DOT mgh DOT harvard DOT edu>): This is the list to email for general support on installing and using FreeSurfer. You need to subscribe to the list before you can send messages to it, and you need to send your messages from the email address with which you subscribed. (This prevents spam.) Messages sent to this list are read by FreeSurfer developers and user community, and they are archived (old archive | new archive).

This is not intended for support of issues pertaining to the Martinos Center and FreeSurfer (for instance, /space/freesurfer and /usr/pubsw/packages issues should use the martinos-tech list).
Send mail to the list at

Please use this list if you are a NMR or Martinos Center user and have general questions about software available to the Center. This list is appropriate for questions about unpacking data or other data processing issues, and for general policy questions. Emails to this list will be read by other NMR and Martinos Center users, as well as the FreeSurfer developers.

  1. What you can do for FreeSurfer: Unable to find documentation on some command or process? Once you figure out how to do it, add documentation for everyone else! To contribute to the Wiki, you will need a WikiUserName. Please see GettingAccess to obtain a WikiUserName and then document away. To create a new page once you have an account, just goto the URL you want to create. For instance, goto this link for a page you would name MyNewPage: and note the link that says 'Create new empty page'. Just click on that and type away (but please don't use MyNewPage as a page name!).
