Display a file dialog in which you can select the NMR data set to open. Typically you will select an Agilent ".fid" directory, an Agilent "fid" file, or a Bruker "fid" or "ser" file, or an NMRView (.nv). If the file represents an FID, the file will be opened and the first row of raw data displayed. If the file represents an NMRView format dataset, the dataset will be displayed (vector for 1D or contour plot for 2D or higher). The dataset will be displayed in the currently active spectrum window.
Display a file dialog in which an NMRView format dataset can be opened. The dataset will not be immediately drawn. Instead use the attributes panel to choose one or more datasets to display in a window.
Create a new spectrum display window. A dataset can be added to the window using the Attributes dialog or by using the Open and Draw menu item.
NMRFx Processor maintains a list of recently opened datasets. Use the attached menu to select one of these to be opened and displayed in a spectrum window.
Create a PDF file containing a rendering of the currently active spectrum. Note: at present, only the active spectrum chart in a single window will be exported to the file.
Create an SVG file containing a rendering of the currently active spectrum. Note: at present, only the active spectrum chart in a single window will be exported to the file.
NMRFx Projects are similar to NMRViewJ projects in that they consist of a main directory and a series of subdirectories. Each subdirectory contains data for a particular data type (datasets, peaks, molecules etc.). Data is stored in simple text files (rather than the STAR format used in NMRViewJ). NMRFx has a built-in copy of Git, a version control system allowing it to keep a history of project changes.
Open an existing project. Use the file browser that appears to browse to the directory containing the project directory. Select the project directory and click Open.
This is a sub-menu containing a list of recently used projects. Choose an entry from the menu to open that project. Entries in the list show the last three elements of the path to the directory to help you in recognizing projects and distinguishing projects with the same name.
Save the project into the various project sub-directories. All the component files of the project are over-written. Then a Git commit is done to maintain to record the differences from the previous state of the project.
Save the project into a new project directory. A file browser will appear that will allow you to choose a directory location in which to save the project.
Delete the active spectrum chart from a window that has more than one chart in it. The remaining charts will be resized to fill the empty space.
Horizontal. Arrange the spectrum charts in a window with multiple charts such that they occupy a single horizontal row.
Preliminary support for synchronized axes. All the spectrum charts in a single window will be synchronized across dimensions that share the same label. Changing the x, y and plane values in one window will result in the other windows being redrawn so that they share the same values on similar dimensions. There is not currently a method to restrict the synchronization to specified axes, remove synchronization, or synchronize spectrum charts in different windows. These features will be coming in a subsequent version.
Adjust the referencing so spectra are aligned with each other. Alignment happens between spectra that are displayed in the same window. They can be in separate charts within the window, or multiple datasets within a single chart. Alignment occurs only between the dataset dimensions on the x and y axes (not planes). Alignment is done by peak picking the spectra (if peak picking has not already been done) and adjusting the referencing such that the distance between nearby peaks is minimized. The first dataset of the active chart is the target dataset. Other datasets are aligned to that dataset. Dataset parameter files are written to save the new referencing. This process (in current implementation) can be slow if there are a lot of peaks. Because of this it's a good idea to have the window display zoomed in somewhat.
Display the spectrum analysis window. This allow you to measure intensities in a specified region of the spectrum (area with the crosshairs).
Display the Console window. The console can be used in Jython (Java version of Python) or R (statistical language) modes.
Show a table of currently opened datasets. Each row of the table shows the dataset name, number of dataset dimensions, default contour level, scale value, default contouring parameters and reference information. Reference information is displayed for a single dimension at a time. A pop-up menu on the DimN header allows you to choose the display dimension. The Draw menu at top of the Dataset Table window allows you to draw selected datasets in a variety of arrangements.
Display the spectrum attributes window.
Display the Processor control window (it appears automatically if you open an FID)
Display the Scanner window. The scanner can be used to process, display and analyze sets of spectra.
The Peak tool allows the user to work with peaks and their peak lists. Users of NMRViewJ will recognize it as being similar to the Peak Inspector and having capabilities of the Peak Reference tool.
The Peak Navigator will appear as a tool bar at the bottom of the current spectrum window. It allows stepping through a peak list and updating the spectrum display to a region around the current peak.
This menu action will link peaks that have common labels. Once linked they will move in synchoriny when using the Peak Slider, and changing the label for one peak will change the label for all linked peak dimensions.
The Peak Slider will appear as a tool bar at the bottom of the current spectrum window. When present peaks that are linked to each other will move together when any one peak is moved. The toolbar provides tools for freezing (and "thawing") peaks into the current position so they can't be moved.
Various menu items for showing and windows. The menu items available are platform dependent.
Open the default web browser and display the online documentation.
Open the default web browser and display the first NMRFx Processor publication. Please cite this reference when publishing manuscripts describing research that used NMRFx Processor in the analysis.
Display a file dialog in which you can select the NMR data set to open. Typically you will select an Agilent ".fid" directory, an Agilent "fid" file, or a Bruker "fid" or "ser" file. The file will be opened and the first row of raw data displayed.
Display the attributes panel for controlling how your spectrum is displayed. The attributes panel in NMRFx is designed to work much like that in NMRViewJ (though the code is completely different).
Refresh the current display. Useful if a display parameter has been changed, but the display didn't update automatically.
Halt the drawing of the current display. Especially useful for datasets that take longer than a few seconds to draw.
Adjust the horizontal (and vertical for 2D spectra) plot limits so the entire dataset is displayed
Expand the view to display the area between the crosshairs.
Zoom the display in (showing a smaller region of the spectrum). When the mouse pointer is over this icon you can use the scroll wheel (or scroll gesture on trackpad) to zoom in or out (Scroll control works the same on both the In and Out icons).
Zoom the display out (showing more of the spectrum). When the mouse pointer is over this icon you can use the scroll wheel (or scroll gesture on trackpad) to zoom in or out (Scroll control works the same on both the In and Out icons).
Adjust the vertical scale of 1D spectra so the displayed region of the data mostly fills the vertical expanse of the plot window. Adjust the contour level of 2D spectra to be 5 times an estimate of the noise level in spectrum.
Adjust vertical scale (or contour level for 2D) so peaks appear higher. When the mouse pointer is over this icon you can use the scroll wheel (or scroll gesture on trackpad) to raise or lower the scale (Scroll control works the same on both the Higher and Lower icons).
Adjust vertical scale (or contour level for 2D) so peaks appear lower. When the mouse pointer is over this icon you can use the scroll wheel (or scroll gesture on trackpad) to raise or lower the scale (Scroll control works the same on both the Higher and Lower icons).
Peak pick the spectrum. The region picked is the currently displayed window or the region contained between the crosshairs (if they are present). The threshold level used for picking 2D and higher dimension datasets will be the current contour level. The threshold for 1D datasets will be the position of the black, horizontal crosshair. Picked peaks will be displayed and the peak information immediately saved in a text file in the NMRViewJ .xpk format in a file in the directory containing the dataset. If the spectrum already has a peaklist then the new peaks will add or replace existing peaks depending on whether peaks are present in the pick region. If peaks are present, the current list will be cleared and replaced with the new peaks. If no existing peaks are present in the region, then the new peaks will be appended on to the list of existing peaks. Peaks can be selected, moved and resized with the cursor in Selection mode. This is a very early implementation of the peak tools. Full peak analysis should be done in NMRViewJ until more peak tools are added to NMRFx Processor.
NMRFx can display contour files of the processed spectra, but it does not have has many display controls as NMRViewJ. Selecting this menu option will tell your operating system to open the dataset. Installations of NMRViewJ normally configure the program as the preferred renderer for NMRViewJ datasets so it should open and display the dataset. Versions of NMRViewJ before 9.1 would not open an already open dataset. Starting with 9.1 you will be prompted to reopen the dataset, so version 9.1 is the preferred renderer to use in combination with NMRFx.
The chart icon can be dragged onto the existing window to add a new chart into the current window. As soon as you click and start dragging the item rectangles will appear on the sides of the current window. Drag and drop the chart icon into one of these window to add a new chart at that location. Once you have more than one chart you will only be able to add new charts in the existing orientation (horizontal or vertical).
The crosshair can be in one of two modes. In Crosshair mode it is used to position crosshairs. In Selector mode, it is used to select, move and resize peaks.
Zero, one (X) or two (X and Y) menus will be displayed depending on the dimensionality of the displayed dataset. These can be used to specify which dataset dimension is displayed on the corresponding axis. For example, a 2D HSQC dataset would have a single (X) menu with choices like 1:HN and 2:N. Selecting 2:N, would switch the display so that the N15 dimension is along the X axis, and the H1 dimension is along the Y axis. These menus are not displayed for FID display.
Four text boxes display the current positions of active crosshairs. You can also use these to change the crosshair positions to a specific value. Just type a number into the box and hit the Return key or change the focus to another text box. Note: if the crosshairs are not currently displayed, then the posiiton values represent the current plot limits for the X and Y axes.
Zero, one (Z), or more menus and plane display controls are displayed depending on the dimensionality of the displayed dataset. The menu can be used to jump the displayed planes to selected values (Full: all planes, First: the first plane, Last: the last plane, Center: the center plane, and Max: the plane with the maximum intensity at the position of the black crosshairs).
Display the phasing tool along the left edge of the spectrum. Phasing is not yet active for datasets that are not actively the result of processing an FID in the current session.
Display horizontal and vertical slices through the spectrum at the position of the black crosshairs. This menu is not displayed for FID display.
Display both the real and imaginary parts of 1D vectors. This menu is not displayed for dataset (spectrum) display.
At the left side of the data display are two controls, a combobox near the top, and a slider control along the left edge. Typically in 2D, phase sensitive, NMR spectra two data vectors are collected for each time point which differ from each other in the phase of one of the pulses by 90 degrees. With higher dimensional datasets an increasing number of data vectors are collected for each time increment. The combo box at top can be used to select which of the group of data vectors associated with a given time increment are to be displayed. This can be useful in determining whether you've set up the right type of data combination operations.
The slider control can be used to scroll through all the 1D vectors along the active dimension. As you slide the control any current processing operations for the active dimension will be applied to the vector before display.
