Please read ALL the information below to help you install and then use NUTS.
To obtain a copy of NUTS:
Go to the Acorn NMR website and download the appropriate version of NUTS for Windows or for Mac. For Windows the downloaded file is zipped (.zip) and you must have a utility to un-zip the file and the proper password.
To obtain NUTS password and license files:
You must be a user of the UCD NMR Facility for us to issue you a NUTS password and license file.
Contact Jeff de Ropp to request the password and license files needed to install and activate NUTS.
To install NUTS on your computer:
1) You will be asked to supply the password to un-zip and install NUTS program files onto your disk. It is preferable to create a separate directory (folder) for NUTS before you un-zip the files. The password is only needed once.
2) The license files (license.nmr and sam.dll, the latter only for the Windows version) are then required to run NUTS properly after installation. Place the license.nmr and sam.dll files into your main NUTS folder. Then double click on nuts.exe (or run NUTS from the Windows Start tool, or from a shortcut you create, its up to you). The NUTS program will start and if the licenses are installed correctly the first panel you will see in NUTS will give information stating that your copy of NUTS is licensed to the NMR Facility of UC Davis. You are now ready to use NUTS.
Read the installation instructions on the Acorn NMR website (the same URLs where you downloaded the software) for more info if needed.
The only other thing you need to do to proceed is get your NMR data from the spectrometer to your desktop. This is best done via the internet.
Importing Bruker XWINNMR data into NUTS:
You cannot connect directly to the NMR spectrometers. First you must place the data on the NMR server. This can be done either from the Windows computers on the 500/600 or from the Linux computers on the 400/7T. The data must then be transfered via FTP (or Fetch on the Mac) from the NMR server to your desktop. Bruker data "files" are actually directories. The parent directory contains several subdirectories as well as plain files that must all be transferred, and NUTS will not work unless the original subdirectory structure of the Bruker is maintained. A Windows based FTP program with recursive FTP capability like Secure FX or AbsoluteFTP is needed; Mac users can utilize Fetch. Once the data is on your hard drive, use the File pulldown menu in NUTS and select:
Then select in succession the parent directory name and Expno you want (these appear in Windows as folder icons). Lastly select the file called fid, which is the actual data.
The Bruker fid should now appear on the screen in NUTS. You can proceed with processing the data (FT and etc).
Importing Varian Vnmr data into NUTS:
Data on the Chem Varian NMR spectrometers is backed up automatically every hour to the Chem NMR server. The data can be transfered via secure FTP from the Chem NMR server to your desktop, or you can use a CD to transfer the data. Varian data "files" are actually directories. The directory contains several files that must all be transferred, and NUTS will not work unless the original subdirectory structure of the Varian dataset is maintained.
A Windows based secure FTP program with recursive FTP capability like Secure Shell Client is needed if you elect to transfer data via FTP; Mac users can utilize Fugu.
Once the data is on your hard drive, use the File pulldown menu in NUTS and select:
Then select in succession the directory name and then the file named fid, which is the actual data.
The Varian fid should now appear on the screen in NUTS. You can proceed with processing the data (FT and etc).
Note: the Chem NMR server only allows secure (encrypted) FTP access.
We have written a very short guide for using Nuts. Although this guide was written to assist those processing Varian data it should also be useful for those processing Bruker data in Nuts.
Macros for processing Varian 2D data
The best way to process 2D data in NUTS is by using macros, which are small files that consist of a series of commands to automatically process various kinds of 2D data. NUTS comes with a few generic 2D processing macros in the Nuts/mac folder; all are named with a .mac extension. Additional macros appear in the Nuts help files for processing 2D data, from which they can be copied and pasted (using a text editor) into .mac files if you wish. Here are a few macros written for processing the common kinds of 2D spectra collected on the Varians.
The NUTS program comes with Help information accesible by a pull-down menu on the task bar. Additional NUTS Help and documentation info is present on the Acorn NMR web site. Since the UCD NMR Facility is a registered user, anyone of us can request assistance directily by emailing support@acornnmr.com. On the Davis campus you can also contact jsderopp@ucdavis.edu.
