Show Data Block History


Show data block history: The history of data manipulations is stored within the spectral multifile. In order to view this information select ' File info → show history' and select the data block of interest.
 
The information includes:
 
1.  data source, time and data of import (block of original data).
2.  time and date of data block creation (data block of preprocessed, derivative, and 3D -FSD spectra)
3.  parameters of preprocessing (derivatives, cut, smooth, interpolate, baseline correction, quality test, etc.)
 
Additional information is available from the log-file.
 
show manipulations Screenshot of the 'Show data block history window' window (example: history of the data block of derivative data)

 

Show Parameters


Displays parameter of the following data parameter blocks:
 
1.  Instrument parameters
2.  Measurement parameters
3.  Additional data acquisition parameters

 
Detailed information on the data parameters is available in the following chapter of this help manual. Additionally, the data parameters can be modified using the function Edit Parameters of the 'File Info' menu bar.
 

Edit Parameters and HSI Metadata


This option can be used to change and modify parameters and metadata of the currently active HSI data file. The 'Edit parameters' window is available by selecting the option 'Edit parameters' from the 'File info' menu bar.
 
edit parameters
Screenshot of the 'Edit parameters' window. Please note that the parameters LWN, UWN, WVS and NOD define the spectral vector and thus
represent internal program-wide variables that can have variety of effects when changes are made. The same applies, in principle, to XDI
and YDI which denote the number of pixel spectra in x-, and y-direction of the given HSI (see below) for details.

 
 
Overview on the instrument, measurement and additional parameters, or metadata used by CytoSpec:
 
Instrument parameters: Measurement parameters: Additional data acquisition parameters:
 
INS - instrument type LWN - starting wavenumber TOS - type of spectra
MAN - instrument manufacturer UWN - ending wavenumber NOS - number of scans
SRC - source setting WVS - wavenumber step XDI - number of pixel in x-direction
BSP - beamsplitter setting NOD - number of spectral data points YDI - number of pixel in y-direction
FIL - type of optical filter DAT - date of measurement NSP - number of spectra
DET - type of detector TIM - time of measurement SZX - area size in x dimension (µm)
VEL - scanner velocity PHC - phase correction mode SZY - area size in y dimension (µm)
LAS - laser wavenumber PHR - phase resolution SAM - sample name
AQM - acquisition mode PIP - phase interferogram points SAF - sample form
SNG - signal gain ZFF - zero filling factor OPN - operator name
    RES - nominal resolution AS1 - additional sample information 1
    APO - apodization function AS2 - additional sample information 2
    APT - aperture size (┬Ám) AS3 - additional sample information 3
    STY - step in y-dimension (µm)    
    STX - step in x-dimension (µm)    

 
Parameters highlighted by red color should be carefully modified since these parameters are used by the CytoSpec software. Modification of these parameters may cause malfunctioning.
 
Changes of the parameters highlighted by red color are tracked and checked when leaving the 'Edit parameter' window. In case of errors or data inconsistencies an error messages will be displayed. The CytoSpec program also makes suggestions of how to change incorrect HSI parameters (see command window below).
