Data Transfer from NMR Workstations

NMR Workstation Hostnames

Use the following hostnames for the Varian (or Agilent) spectrometers:

Follow the separate instruction given during training to transfer data from the two Bruker spectrometers.

NOTE: The NMR computers are inaccessible from any computer with an off-campus IP address. Please use UCSB VPN or campus networked computers to transfer data. In rare cases, you can use a USB stick to transfer data directly from the computers, but this is not recommended due to virus concerns.

Please note that you should use the secure FTP protocol (sftp) for data transfer from the NMR workstations to a Windows or Macintosh based system. From a Unix or Linux system, secure FTP (sftp) or secure copy (scp) both work fine with the NMR workstations for data transfer.

CAUTION: Be carefull not to download or install any adware on the web site or accept to install adware during installation.

Force Raw or Binary Data Transfer on Mac

If an error message in Mnova indicates data corruption, especially on some Mac computers, data may be corrupt due to the default text transfer mode for files without or with an unrecognizable extenstion. Try to manually set the transfer mode to raw or binary mode. In FileZilla, go to Edit->Settings ...->Transfers->FTP: File Types, check "binary" under "Default transfer type" and uncheck "Treat files without extension as ASCII file". WinSCP running under Windows does not have this problem.

For Windows

WinSCP is the best, free secure FTP program. Download this program from its official website and install it. If you encounter an error message when using drag and drop for data transfer in newer version of the software, you may have to adjust the drag and drop preference. Click Preferences and go to Other General Options->Preferences. Then, click Transfer->Drag & Drop and select Use temporary folder.

When making a connection to a remote computer, click New to create a new session, enter hostname (see below), username and password, and select SFTP under Protocol and check Allow SCP fallback, and save the session setup for future use. DO NOT save the password on a shared computer. With a saved password, anybody can click the saved session and log in and the person can delete and modify your files at will.

To log into the remote computer, highlight the saved session and double-click it or click Login.

WinSCP

Alternatively, you can use Filezilla for sftp (see Macs section below).

For Macs

Download FTP client software Filezilla or Fugu , both free. Fetch is good too but it is not free.

To use Filezilla, enter host name, username and password and set port number to 22 to use sftp (see screenshot below). Click Quickconnect to make the connection.

Filezilla

Alternatively, you can also enter under Host sftp://nmr600.chem.ucsb.edu or simply sftp://nmr600 for department networked computers and leave the port field blank.

Filezilla
