Uploading Digital Data to the ATC   UPDATED (10/28/15)

The ATC uses a Secure FTP (SFTP) server for uploading digital imaging, treatment planning, and verification data from clinical trial and registry participants. This server uses the SSH network protocol and offers several advantages over conventional FTP, including encrypted transport of usernames, passwords, and data, and compatibility with most firewall configurations.

Please note:

  • All network data submisions to the ATC must use the Secure FTP server, ITCsubmit.wustl.edu (IP address
  • An SFTP account (username and password) can be obtained by contacting the ATC (314-747-5414).
  • Please read Instructions for configuring SFTP clients (WS FTP Pro, Filezilla, WinSCP3, and Linux sftp)  UPDATED (6/14/06).
  • SFTP client software, both commercial and open-source, is broadly available. The free/open-source FileZilla software is available for Windows, MacOS, and Linux. Windows SFTP clients include WS_FTP Professional (commercial) and WinSCP (free/open-source). For Linux systems, both graphical (gftp) and command-line (sftp) programs are included with most distributions.
  • Problems in connecting to the ATC SFTP server, may be caused by your institution's firewall configuration. An outbound connection from your computer to TCP Port 22 on host ITCsubmit.wustl.edu is required. (Although allowing such a connection is safe, it is sometimes disallowed by default.)  Please consult your local firewall/network administrator.
  • The ATC Server Access Test web page can be used as a check of network connectivity between your computer and the ATC SFTP server.   (Here is an alternate link to the Server Access Test page using the IP address of the ATC server.)   UPDATE (9/23/08)
  • Please direct questions regarding digital data submission to Walter Bosch (itc@wustl.edu).
