By default, VnmrJ is set to automatically process NMR data when a FID file is opened. If you prefer to process your data using the parameters that were stored in your FID file, you can do so. All you need to do is to disable the autoprocessing feature: click Edit in the main menu, then click on System setting … to open the System setting window, click on the Display/Plot tab and uncheck Process data on drag-and-drop.
Now, when you open a FID file, VnmrJ doesn’t execute autoprocessing. You can retrieve the parameters (phase, integrals, scales, plot regions, etc.) stored in the FID file, and reprocess your data – just type wft or wft2da (for 2D data).
