For the images, I am using data from titrating SUMO with PML.
If you would like to follow along, use these data files. (pml_data.tar.gz)

First, start NMRViewJ.

Next, in the tcl interface of NmrViewJ (near the bottom of the screen), navigate to the directory containing the NvMap tcl files. Once you get to this directory, type in "source source.tcl" in the tcl interface. If you need more information about how to navigate using the cd command, then look here or here. 
 

From the main menu, load your reference peaklist by clicking on the "Assign" menu, selecting the "Peaks" choice, and then clicking on the "File" button, selecting "Read List", and picking your peaklist.









Load each dataset by clicking on the "Datasets" menu, selecting the "Open Datasets" option, and selecting your dataset.



Open the NvMap window by selecting peak transfer from the NvMap menu in the main NMRViewJ window. The window should look like:  







Select a reference peaklist in the top pulldown menu.  









Select a dataset from the side pulldown menu.  









Type in the peaklist name or select a peaklist using the "List..." button. 








If desired, add another line for entering another test dataset by clicking on the "Add Line" button.  








I have added several more lines here. 












I have selected four more datasets and specified their peaklist names here.  











Finally, push the "Transfer peaklist(s)" button, and wait a few seconds for the calculations to complete.
