LMCF Server and data transfer

Purpose of the LMCF file server

Moving data between departments and buildings at Duke isn't always trivial. You may be able to simply use your departmental server directly, or external drives may be adequate for your needs. LMCF provides a server to make it easier to move data around and store it while you are working on it. The server is accessible from anywhere at Duke, from both the University and Medical School buildings. It is intended to act as a means of transfer and temporary storage but not unlimited long-term storage of all your images. (Duke Box offers 50 GB of web-accessible storage space fully supported by Duke and might be a good option, or you might have other resources available to you).

Rules for files in LMCF

This is quite a challenge. Please appreciate we have several hundred users and more than a twenty systems, and microscopes generate A LOT of data. Our aim is to keep the computers fairly clear and make sure you can move and access your data safely and easily.

You are responsible for your data.

Please move your data from the acquisition computers -

  • They really aren't safe places to keep anything
  • Please either move the data (rather than copy) or delete the local copies after you have them safely elsewhere
  • We may delete any files without warning if space is required for experiments
  • (Caveat for small files, we understand sometime it is useful to store a reference file (eg to reload settings) so it is fine to keep permanently a small volume of data in a clearly labeled folder)
  • Any files on any computer should be in a folder with your full name or netid on the data drive (please don't use the desktop or "my documents" as it buries the files in places less easy to maintain)

Files on the transfer server:

  • You get a quota (25 GB), use it how you like but if your space is full of archive files you might not have space for your new stuff.
  • Any files left on the server when you leave Duke (Criteria for judging this: your email no longer works) will be deleted
  • Your files can be seen only by you and LMCF staff (this is a good way of getting images to us)

When you are in LMCF . . .

Log on to the microscope or workstation computer as you do normally

You can save directly to the server or to the local hard-drive and move the data afterwards. In general we recommend saving directly to the data drive on the computer and moving the data when you are finished and have closed the software. Sometimes the software has problems saving to remote locations, and often for timelapse etc the speed isn't good enough. Moving rather than copying data really helps LMCF keep the computers clear.

Most computers have multiple hard-drives on those systems and you should save data to the data drives rather than the C:/ drive. Please don't use the desktop or "my documents". Storing data is labeled folders on the D:/ drive or similar helps make data management easier and windows working better.

How do I connect to and use the LMCF server?

You can connect to the server from any of the LMCF microscopes/workstations or the PC's or Macs in your lab using Samba (SMB). On a Windows PC this is called a “share” or a mapped network drive, on a Mac use “connect to server”

Use your netid and password to authenticate to the new server (no special password set up is required). On most PCs you need to enter WIN\netid for the user name rather than just your netid.

The paths to map/connect to are (you will receive this is an email too when your account is set up)

Mac (CMD + K to connect to server): smb://oit-nas-nb12pub.oit.duke.edu/lmcf
Windows (right click my computer, map drive): \\oit-nas-nb12pub.oit.duke.edu\lmcf

This should work from anywhere at Duke. If you need to access the data offsite (eg at home) you can use VPN to gain a Duke IP address.
