FAQ 2003-03.1: How can I create 2D plots with 1D spectra on the side?
NMR staff changes
Mark Miskolzie joined the NMR support team. Mark replaced Gerdy Aarts who retired recently. Mark can be reached in WB-13 (492-2573).
We wish Gerdy all the best for the NMR-free part of her life and thank her for all efforts to keep magnets filled and spins spinning over many years.
How can I create 2D plots with
1D spectra on the side?
The entire procedure is now available within the EZ NMR system in a much simplified form. There are two ways to achieve this: with the click of a button or by using one of two macros called pl2d1dhh or pl2d1dhx (hh for homonuclear experiments such as GCOSY, GTOCSY, TROESY etc. and hx for all heteronuclear experiments, e.g. GHSQC). If the button is used the software decides automatically which macro to call. The fundamental difference is that the macros give you a variety of options while the button does not.
To use the macros or the button it is a prerequisite and assumed that
Experiment numbers can be freely selected but the use of the macro or button has to be from within the experiment that contains the 2D spectrum. In general, everything is done in the experiment that contains the 2D data!
A summary in PDF format for both the homo- and heteronuclear case can be found here. As an example, for homonuclear experiments, here is what happens when using the macro pl2d1dhh or clicking on the button 2D with 1D in the Plotting section of EZ P+P:
This is the easy and most often used way for that task. More can be done but only by using the macro pl2d1dhh with arguments (a maximum of 5 arguments can be specified).
The heteronuclear version can accept up to 7 arguments and a description analogue to the one given above for the homonuclear case is in the PDF document to allow easy printout.
This may look rather overwhelming but it can be as easy as clicking on the correct button and the rest is automatic and will in nearly all cases lead to the desired result. You may want to give this a try!
