Sparky displays processed NMR spectra. You find, assign, and integrate peaks using a graphical interface. Spectra for input to Sparky can be produced with the processing program NMRPipe (from the NIH), or Felix (from BioSym), or VNMR (from Varian), or XWinNMR or UXNMR (from Bruker). After picking, assigning and integrating peaks you can produce peak lists showing chemical shifts, volumes, linewidths, .... Atoms have groups or residues associated with them to aid assignment of proteins, dna and rna. You can work with any number of 2, 3 or 4 dimensional spectra simultaneously.
This is version 3.66 of the manual, last revised March 3, 1999. You can get a Postscript version or the latest html pages, images, and Postscript in tar or zip format from the Sparky web site (http://www.cgl.ucsf.edu/home/sparky). To search for specific words you may prefer the single file html manual. The manual is part of all Sparky distributions. It can be found in /usr/local/sparky under Unix or Linux and in c:\Program Files\sparky under Windows.
