Command lt opens the peak list which can be saved in the text format and you can select what goes into the spectrum. In the end you will have several spectra with picked and integrated peaks. In sparky you can turn on display of X and Y 1D slices by typing vS - when you put your mouse over the peak you will see 1D lines of real data and fitting curves. IMO even the best fitting algorithms will fail when fitting areas with many overlapped peaks. If you want peak volumes then it's a very good idea to check the quality of peak fitting. When peaks overlap then they need to be fitted simultaneously. You can integrate peaks either one-by-one or in bulk - depending on how many are selected. If you don't want the peaks to move then you can lock the by typing pk. The fitting routine moves peak positions to fit the data better - and it is not always accurate at that. You can select multiple peaks by holding Shift key while clicking on the peaks. Command it - gives access to options used by the integration algorithm. Command pi integrates selected peaks - runs fitting and calculates peak volumes. Hand-typed commands in sparky give you very fast access to all functions of the software.Ĭopy-pasting peaks in sparky from one spectrum to another is very simple (click into first spectrum, type pa - select all peaks, oc - copy peaks - ornament copy, click into another spectru and type op - paste). Mostly because of familiarity and the mechanical memory of typing commands. If I had to do this analysis myself I would use Sparky. Links (must register on Bruker site to access): windows version and linux version. Maybe you'll benefit by changing your title to something like "Software to analyze 2D T1 and T2 relaxation rate data?" - that way the question will probably attract answers about other programs.Īt the 50th ENC Clemens Anklin showed a program written at Bruker that does that sort of analysis easily.
Unfortunately I can't answer for nmrDraw, because I only use it when I process data (FT, etc) with nmrPipe.
