The brand-new, top-modern
successor software for Spekwin32

Spectragryph 1.0
 

 

File menu

The File menu contains all functions to Open, Save, Print and Export spectra.
At the bottom you will find a list of the most recently used Spekwin32 files (only *.spv files).

1. Menu Item [Open]

  • For loading of spectra.
  • Several files can be selected simultaneously in the usual manner.
  • While loading the spectra, the status of the reading procedure is displayed in the middle part of the status bar.
  • If possible, the x and y axis types are chosen according to the most recently opened spectral file.
  • The following file formats are currently recognized (find a zipped collection here):

    file extension description
    *.abs, *.trm, *.ssm, *.irr ,*.lib ASCII file formats of StellarNet's SpectraWiz software. File extensions explained:

2. Menu Item [Open unknown binary file]

  • Assists you in getting out spectral information from binary files with unknown data formats.
  • After opening your unknown file, a pre-formatted Excel template file opens. The unknown file's content has been put to the clipboard. Please paste this to cell A1 of the Excel template.
  • The first line shows your file's name and filepath. The columns show the file content "as-if" the data was in a certain number format (as there are integer and float types coming with different byte sizes and Endianness).
  • Useful content could show up in any column, normally block-wise. By conditional formatting, the template highlights datablocks with useful numbers.

3. Menu Item [Paste Data from Clipboard]

  • To transfer arbitrary data from Excel or Origin or even any text editor into Spekwin32.
  • Required are at least two columns, where at least one contains the x axis values.
  • Just select the desired range of data, and copy&paste into Spekwin32.
  • Works with multiple columns, "x y y y" and "x y x y x y" arrangements are accepted. Axis types can be defined in the line above the data columns. Default types are "wavelength" and "absorbance", if no other information is detected.
  • Optionally, there can be names for the spectra in the line above the axis type descriptions.
  • Hint: Within Excel, use the keyboard shortcut CTRL+SHIFT+Arrow(down, or right) for automated selection of whole data blocks. Do not select completely empty columns.

4. Menu Item [Save]

  • Saving current content of the graph window.
  • Graph will be saved with the file name and file type from the last use of "Save as..." On first use, "Save as..." dialog will appear.

5. Menu Item [Save Data as]

  • Save the data of currently displayed spectra. A "Save as..." dialog appears for file name, type and path.
  • There are 5 data file formats to select from:
    • spv files for fast and space-saving storage and reading in again of spectra in any composition.
    • spc files for saving of single spectra in Thermo Fisher's quite common file format. More about Thermo Fisher Galactic spc files here.
    • dx file for saving single spectra in the worldwide used, IUPAC-proposed standard file format JCAMP-DX.
    • dat files for import of values into graphing programs like Origin or Sigmaplot. Sample file. Multiple spectra interpolated get interpolated onto a single common x column.
    • csv fore easy export of the original spectral data for Excel and the like. Sample file. Multiple spectra contained as separately xy paired columns.

     

6. Menu Item [Save for RRUFF]

  • For saving Raman spectra into the native data file format for the RRUFF minerals database. Their software CrystalSleuth allows to create and maintain your own searchable minerals Raman spectra database.
  • Select the spectrum to be exported in the upper dropdown list, use parameters from the input file or put them in yourself.
  • The [Save] button will save the selected spectrum in *.rruff format.
  • Quit the window with the [Close] button when finished.

7. Menu Item [Batch Export Data]

  • Export all loaded spectra as single spectrum files into three file formats (*.spc, *.dx, *.csv). Additionally, all spectra can be exported together as multi-file (same file formats).
  • export data as individual single spectrum files or else as common multi-file.
  • file location: choose to save the files in the same location (the filepathes where the original spectrum files were located), or else together at the filepath defined in the edit box below.
  • A new file name can be defined together with attached successive numbering, or else the legend texts can be used as filenames. Combine both options by selecting both.
  • The [Export!] button starts the file export process; the progress will be shown in the text field and with a progress bar below..

8. Menu Item [Save Plot as]

  • Save current spectra as spectral plot. A "Save as..." dialog appears for file name, type and path.
  • There are 5 data file formats to select from:
    • csv fore easy export of the original spectral data for Excel and the like. Multiple spectra contained as separately xy paired columns.
    • gif files for saving as internet usable pixel graphics, compressed files, 256 colours, resolution: 1350x900 pixels.
    • bmp files for saving as lossless pixel graphics, big files, resolution: 1024x768 pixels.
    • wmf files for saving as freely scalable vector graphics of small file size, recommended best use for Windows Office applications like MS Word or MS PowerPoint.
    • tif files for saving as rather small lossless compressed files with 32bit colours, best for printing, resolution: 1350x900 Pixel.
    • png files for saving as small lossless compressed files, the internet picture format of the future, resolution: 1350x900 Pixel.
  • Hints for optimized graphics export:
    With high resolution screen and maximized program window, the standard axes and legend fonts might look rather small in saved graphics. Try saving again with mid-sized Spekwin32 window.

9. Menu Item [Save for Gnuplot]

  • For creation of EPS files.
  • Creates two files with the same name: a Gnuplot parameter file (*.plt) and a second file (*.tat) with the spectral values. The parameter file contains the necessary commands for Plot Title, Axes titling and scaling, second X-Axes, second Y-Axes (if degree of polarization is included), position of the legend box and creation of EPS file with the same name. Before saving, there is a dialog for configuration of these parameters where additional commands can also be included.
  • For this function the following parameter files must exist in the program folder : gexit.plt, ginit.plt, pola36.plt, postcol.plt, postmon.plt (included in spekwin32_install_en.exe). Tested with Gnuplot 3.7 for Windows (32bit). You will find more information on Gnuplot here.

10. Menu Item [Copy Data to Clipboard]

  • Copy all data from all current spectra to the clipboard. From there, it can be pasted into text processing or spreadsheet software (like MS Excel or Origin).
  • Spectral data will be saved in x..y..x..y..x..y.. format (each spectrum has its own paired xy values), in case all spectra have the same x values, the format will be x..y..y..y.. (that is: one x column for all spectra).
  • The first line contains the legend texts, second line contains x and y format for each spectrum.

11. Menu Item [Copy Plot to Clipboard]

  • Current graph window is copied as a vector graphics to the clipboard. From there, it can be pasted into graphic or text processing software. For optimized graphics see File/Save as...

12. Menu Item [Print]

  • Prints the current graph window. Select installed printers like usual.
  • For optimized graphics see File/Save as...
  • PostScript files (*.ps) can be produced by printing into a file with a PostScript printer driver.

13. Menu Item [Exit]

  • Terminates the program. Unsaved spectra are lost!
