NMRView stores most all data within a STAR file format as used by the BioMagResBank. The molecular topology, picked peaks, chemical shift assignments, restraints, structural coordinates and other data is all stored together in one file that can be moved from one computer to another. Storing data in this format is preferred to exporting individual chemical shift files and peak lists as it ensures that all relevant information is saved.
NMRView can work with various files on an "ad hoc" basis, but it is very useful to use the new project structure. Projects are sub-directories of a main NMRViewJ project folder and contain folders STAR files, datasets, structures, and saved window states. Datasets can be stored within the project folder, or pointers direct NMRViewJ to other dataset directories. With projects you don't need to explicitly load datasets, as NMRViewJ can scan the dataset folders, including all sub-folders and find and open any NMR datasets. Opening the project will automatically load datasets and the latest STAR file. Saving the project will save relevant information into a STAR file with an automatically incremented name and will also save the state of all opened spectral windows. The Favorites icon on spectral windows will save the current window view to the projects windows folder. These can readily be opened from the Favorites menu.
Like what you see and want to come back to it later? Just click the Favorites Icon (the Heart) in the toolbar of any window and an NMRViewJ window file (extension ".nvw") will be saved into the "win" folder of your project. Select the Favorites menu item in the Window menu to see a list of all saved windows. Selecting a saved window and clicking open will create a window exactly like the saved one. If you're using the premium version you'll also see NMRViewJ canvas files (extension ".ncfx").
