Biomedical Applications of Vibrational Spectroscopy - Hyperspectral Imaging - Chemometrics
 
 


Announcing a new version of our hyperspectral imaging software:
- CytoSpec 2.00.07 -



 
 

August 2023: CytoSpec 2.00.07 (build 372) has finally been released and is now available for download
 
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 2.00.07?
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
