Uploading Data

If you have been asked to send the FreeSurfer team a file, you can either send it via FTP or File Drop. Instructions for both are below.

When sending us data, please keep in mind any restrictions dictated by the IRB protocol governing this data. By default, mgz files (the FreeSurfer file format) have been stripped of any identifying information. However, you may want to consider defacing your data before you send it.

FTP File Exchange

An FTP server is available to which, under special circumstances, files may be uploaded. Also, sometimes special distributions or bug fixes are posted to the server for user download.

Use ftp surfer.nmr.mgh.harvard.edu. Login as anonymous and use your email address as the password.

Example login:

$ ftp surfer.nmr.mgh.harvard.edu
Connected to surfer.nmr.mgh.harvard.edu (
220 surfer.nmr.mgh.harvard.edu FTP server (Version wu-2.6.2-15.7x.legacy) ready.
Name (surfer.nmr.mgh.harvard.edu:fsurfer): anonymous
331 Guest login ok, send your complete e-mail address as password.
230 Guest login ok, access restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.

If you are getting files, then

ftp> cd transfer/outgoing
ftp> get filename.txt

If you are putting files, first change to the file's directory (before logging onto the FTP server), then

ftp> cd transfer/incoming
ftp> put filename.txt

If you want the directory containing the public distributions of FreeSurfer:

ftp> cd pub/dist/freesurfer

The dir command will show directory contents. The get command will download a file to your machine.

For those inside NMR center

Go to /cluster/outgoing and put files in its subdirectory. You can get user transfered files from /cluster/incoming. It takes 5 minutes or so to actually see the files there after the transfer.
