The "Open and Draw" function combines two functions that can also be performed separately. You may wish to do so if you're overlaying spectra or something more complicated.
First, you open the spectrum by going to the Main Toolbar (Figure 3.1, “NMRView Main Toolbar”), clicking "Datasets", and selecting "Open Datasets". Yes, that's plural in case you want to open several at one time. The panel you get looks just like the "Open and Draw" panel, but this one only opens them:
"Opening" a dataset can be thought of as bringing it (the spectrum) into the working memory. From the working memory, you can retrieve it and place it in any spectrum window, including those that already have spectra in them. You can also place the same spectrum in multiple windows, which is handy when, say, displaying the HN-HA region of a NOESY while also displaying the HN-HN region.
If you've going to be examining several spectra in this session, you can select multiple files at the same time in the normal Apple way, by using the Shift and Command ("open-apple") keys while clicking. It is especially convenient to hold the shift key here while the file type is set ot ".nv", because this will select all the NMRView datasets in your range but skip the files that don't have the ".nv" suffix.
Note: NVC used to display some data, such as resonance frequencies, sw's, and axis labels, in the TkCon window when opening the dataset. NVJ seems to only display the text "set 1 1" in the SwkCon window.
If you lose track of what you've brought into the working memory and you try bringing in something that's already there, you'll get an error message:
So if you see this, don't freak out. It's just telling you everything is OK already. Just click "OK" and move on.
Now create a new window into which you'll bring the spectrum. From the Main Toolbar (Figure 3.1, “NMRView Main Toolbar”), click Windows...Add. You'll be prompted to give a name for this window (Figure 3.11, “The Windows...Add panel”), and you can use something descriptive EXCEPT you cannot use a capital letter to begin the name, and spaces in the name are not allowed, but "_" characters are. (Actually, you can use a space if you precede it with "\", as in "fruit\ loops" to yield "fruit loops". But that starts complicating matters, and isn't life complex enough already?) The "rows" and "columns" options allow you to partition a window into sub-windows, should you wish to do so. For most purposes, you can ignore this and leave the selections at "1." Once you've provided a new name and hit "return" or clicked "create," a new "blank" spectrum window appears on your screen (here, I typed "hn_co_cacb" for the name, Figure 3.12, “A new, blank Spectrum Window”).
