the spectra, the status of the reading procedure is displayed in the
middle part of the status bar.

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):

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.

[Save
Data as]
- Save the
data of currently displayed spectra. A "Save as..." dialog

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..

[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.

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.

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.

[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
