March 2024: CytoSpec 2.10.01 has finally been released and is now available.
What is CytoSpec?
The CytoSpec multivariate imaging software package is a comprehensive software solution for creating pseudo-color representations of
hyperspectral imaging (HSI) data using statistical and machine learning methods that exploit the full spectral and spatial (image)
information. It is designed and optimized to work with 3-dimensional hyperspectral data matrices from infrared (IR) or Raman spectroscopic
imaging experiments. Native data formats from different instrument vendors can be analyzed.
What is new in CytoSpec 2.10.01?
- New import filter for
Photothermal *.ptir (hdf5) PTIR / Raman
files
- New preprocessing function of Kramers-Kronig transform (KKT) to transform FTIR specular reflection data into absorbance-like
data
- Function
subtraction revised: tooltips added, improved
usability, dialog box revised
- Instead of instead of Matlab Component Runtime (MCR) R2014a 64-bit, CytoSpec standalone Windows version 2.10.01 requires
the MCR R2023b 64-bit environment to be installed
- Function
water vapor correction slightly modified: tooltips
added, etc.
- Many code improvements and bug fixes
What is new in CytoSpec 2.00.07?
CytoSpec 2.00.06
CytoSpec 2.00.05
CytoSpec 2.00.04
- New functionality of the
PCA-based noise
reduction routine
- New function
edge-preserving denoising
(EPD) available
- A node attenuation filter was added (developer version only). Node attenuation is considered a band narrowing filter
avoiding artifical side lobes (like in Fourier-self deconvolution spectra, for example)
- The univariate imaging function
FWHM imaging
has been added (FWHM - full (band) width at half maximum). This functions permits visualization (imaging)
of band widths variations.
- Many code improvements & bug fixes
CytoSpec 2.00.03
- New function
n-findr multivariate imaging, an
endmember extraction method.
- Function
HCA of chemical images
added: Unlike the function 'HCA imaging', which creates pseudo-color segmentation images based on spectral domain
information, this functions allows hierarchical cluster analysis of chemical images, i.e. of image (spatial) domain
information.
- Many code improvements & bug fixes
CytoSpec 2.00.02
-
Import filter for Renishaw *.wdf spectra files.
With version 2.00.02 CytoSpec supports importing of WiRE 4.0 *.wdf mapping data files.
- New import routine for Renishaw ASCII (*.txt) data files
- Updated
import filter for WITec Raman data (*.txt,
and *.mat (Matlab) format) produced by WITec Project v. 2.1 and WITec Project Four. Note that the Matlab *.mat import filter
is supported only by CytoSpec 64-bit!
- New
import routine for Thermo/Raman data files
acquired by OMNICxi Raman imaging software (v. 1.00 and later). CytoSpec allows importing of Raman maps stored in the
HDF5 data format (*.h5, hdf5 libraries version 1.6.4). Note that the *.h5 import filter is supported only by CytoSpec 64-bit!
- The
import filter for Thermo/Atlus (*.spc) data
files has been completely revised. This filter supports now importing of Atlus mapping version 7 data files.
- New imaging function
create composite images.
This function is available from the context menus of CytoSpec's pseudo-color displays and allows superimposing up to 6
individual image layers.
- Many code improvements & bug fixes
CytoSpec 2.00.01
- First version of a
64-bit stand-alone version of
CytoSpec. CytoSpec 64-bit requires installation of the free-of-charge Matlab Compiler Runtime (MCR) R2014a
64-bit. Matlab is not required anymore for using CytoSpec 64-bit.
- The
graphical user interface has been redesigned
and now features a cleaner look that makes it simpler and quicker to use.
- A new menu bar 'spatial preprocessing'' introduced that contains functions like 'crop',
'interpolate/binning','spatial filtering', 'edge-preserving denoising' (EPD, added later
with v. 2.00.04),'3D-Fourier self-deconvolution' and 'replace NaNs' (added later with v. 2.00.05).
-
Colormaps 'i-jet', 'i-hsv' and 'i-hot'
allow displaying inverted colormaps which are useful to produce chemical images from second derivative spectra.
- The
memory option 'compress' has been
deactivated - this functionality became obsolete with the availability of CytoSpec 64-bit.
- With CytoSpec 2.00.01 functions
chemical movie,
frequency images and
FWHM images were added to demo and commercial
program versions.
- The figure
display options has been removed - this
functionality is now available from the redesigned graphical user interface of CytoSpec 2.0.
- Default folders containing the license key (cytospec.lic), log-files, temporary files and the color text file
(color.txt) were modified. These files are are not anymore located in the CytoSpec program folder, but in the Windows
public user directory (C:\Users\Public\Documents\MATLAB) and usually offers full read/write access.
- Many code improvements & bug fixes
