Processing of NMR data in Topspin
Downloading Bruker NMR data to a local computer
- I downloaded data using Data Server v.5.
I received a ZIP file (or other if you choose). My local folder here is NMR_Data
- When I un-zipped it, I obtained a directory structure including my user name and the instrument name. I need to remove them, otherwise Topspin will not read the data.
- I will copy only the folder enclosing NMR datasets (folders labeled with number) to my working directory (NMR_Data):
- I moved my data folder to NMR_Data. Now I may delete the rest of the tree and the original ZIP file:
- Here is my final result:
I will direct Topspin to this folder following Opening data in Topspin from the data folder on a disk
This has to be done only once - Topspin will remember location of the data.
Opening data in Topspin from the data folder on a disk
Often it is possible to just drag-and-drop the NMR datasets into the Topspin window. However, it is recommended to add your working NMR data folder into the Data Browser panel in Topspin for a quick and reliable access. To do this I need to take the following steps:
- I will make a folder for storage of all of my Topspin data, NMR_Data
- Download my data files into NMR_Data and restructure as described here Downloading Bruker NMR data to a local computer
- Launch Topspin
- Make a right click in the File Browser area to bring the contextual menu:
- In a contextual menu click "Add New Data Dir"
- Click three dots in the dialog box to search for the NMR_Data folder:
- Select NMR_Data folder and click Open :
- In Alias field, type in NMR_Data and click OK:
- Data tab of the File Browser window now has NMR_Data entry:
Any new data added to NMR_Data folder on my disk will appear in Topspin Data tab in NMR_Data.
Known glitches: Topspin on newer Macintosh computers does not open files
Description: Topspin files downloaded to newer Macintosh computers cannot be open in Topspin.
Explanation: Newer OS X versions direct requests for data, by default, to the Apple iCloud storage and only after that - to a local disk system. Topspin becomes confused and cannot open the files.
- Make a folder for storage of all of your Topspin data outside of your user folder: /Users/NMR_Data. Since it is outside of the normal user area, it is not affected by the iCloud glitch. To do this:
- Open Finder window
- hit Command-Shift-G (opens a dialog to enter an explicit path)
- enter /Users, hit Go
- hit Command-Shift-N (to make a new folder in /Users), enter your password (if needed), hit OK, enter NMR_Data as a folder name
- Download your data files into /Users/NMR_Data
- To properly structure your data and add the folder to Topspin Data Browser, see Opening data in Topspin from the data folder on a disk
