March 20, 2017 Spectragryph version 1.0.7 released

New functions:
Read & save the new binary multi-spectrum Spectragryph file format (*.sgd)
Read spectral data files with *.txt file extension (assuming two-column, single spectrum data)
Reading the "Logtext" part of *.spc files and extracting information, saving the logtext for *.spc and *.sgd files
New parameters for "Extract Data": x,y,z position
Editable tab names for all "Views"
Changes:
"Transform to Raman shift" now accepts negative start values (for showing anti-Raman area)
Lower boundary for transmittance values changed from 1E-6 to 1E-10
Bug fixes:
Peak finding didn't work reliably for minima
"area under curve" calculation from "Extract Data" function always used "individual baseline" first, neglected user selection
Line position for center of gravity didn't update after user interaction
Some parameters for "advanced baselining" were not remembered after closing the baseline settings window
Removed interference with short keys (DEL, BACKSPACE, ...) when entering values into edit fields
Fixed erroneous peak position value when using transmittance scale in "Extract Data" function
Fixed error message after showing/ hiding legend
Web address in "About" window works now

Reading of Thermo Noran Wintrace XRF spectral files (*.spc)
Log(1/R) transformation for reflectance spectra
Changes:
Fontsize for peak labels now changing together with axis labels
Improved preset boundary values for "Spectrum part cut off" function
Bug fixes:
Switching plot's x axis from µm to nm now works smoothly

Improved installation routine for support of Andor*.sif files
Improved reading of RRUFF database files (*.rruff) with long header
Resolved file format collision for Thermo Mattson *.abs, StellarNet *.abs and Avantes *.abs8 files
Improved reading of Avantes Avasoft 8.x files, making compatible to new Avasoft version

Jan 31, 2017 Spectragryph version 1.0.5 released

New functions:
Reading of timestamp information for Agilent 8453 *.kd kinetic series
Kubelka-Munk transformation for reflectance spectra
Multiplicative scatter correction (MCS) for chemometrics preprocessing of NIR files
Standard normal variates (SNV) for chemometrics preprocessing of NIR files
Detrending of global slope, for chemometrics preprocessing of NIR files
Changes:
Showing popup explanation for advanced baselining & smoothing
Peak Labels: lower limit is now "2" for x, y digits setting
Bug fixes:
Export as JCAMP-DX (*.dx) always using "." as decimal separator
Improved reading of USGS reflectance spectra (U.S. Geological Survey, https://speclab.cr.usgs.gov/spectral-lib.html)
Improved reading of Horiba Labspec *.ngs spectra files
Improved reading of HP/ Agilent 8453 *.sd spectra files

Jan 26, 2017 Spectragryph version 1.0.4 released

New functions:
--
Changes:
EEM plot with movable, hideable legend
Tabs with spectra plots get numbered names, for better distinction
Colour palettes: removed white, yellow, light components for better visibility and printability
Bug fixes:
Cut off spectrum part: allow entry of negative values as boundaries
Change background colour: immediate colour change after selection
Spectrum plot: Grid & Axis colour gets adapted on background colour change, for better visibility
Normalize (area): correct results for spectra with "Raman Shift" x axis type
Advanced Baseline: improved positioning of linear baselines
Spectrum plot: y axis tick values with proper amount of positions and less rounding
Spectra tabs: error-free opening a new tab after closing all tabs before
Peak labels: now works also for cut-off tabletop peaks
Reading ANDOR files: on some systems, Spectragryph didn't start at all, due to DLL dependencies. Should work now on all systems and read ANDOR *.sif files

Jan 17, 2017 Spectragryph version 1.0.3 released
New functions:
Spike Removal: option for maximum spike width
Averaging: "numbering-based" grouping option
Reading of ANDOR Solis spectral files (*.sif), works on single- & multi-frame files and kinetic series
Reading of HP/ Agilent 8453 Chemstation kinetic series (*.kd)
Reading legend texts of HP/ Agilent 8453 Chemstation multifiles
Reading of Avantes multichannel files with differing pixel numbers between channels
Reading timestamps for WinAspect kinetic series
Changes:
File extension gets removed from legend texts,when filename is used as legend text
Clicking on a spectrum scrolls legend to show spectrum name if many spectra loaded
Advanced Baselining: 5x increased speed for large spectra (> 5000 data points)
Improved reading speed 25x for Agilent 8453 *.sd files
Updated supporter list in About section
Bug fixes:
Extract Data: now takes the highest instead longest-wavelength peak when using the peak position parameter
Batch Export: works now with all parameter combinations
Switching x axis type from wavenumbers to wavelengths sometimes resulted an error message
Clicking on spectrum or legend text now triggers all required changes within the Plot ribbon
Improved behaviour for peak finding

Nov 11, 2016 Spectragryph version 1.0 released
Spectragryph is an all-new software, and at the same time based on proven algorithms developed for Spekwin32 over 15 years. This is the first entry of the Spectragryph change history, and I am sure it will change the history of spectroscopy software.
