File Information

Show History

Show Instrument Parameters

Show measurement Parameters

Show Additional Parameters

Edit Parameters

Help is available for the following functions of the 'file info' pull down menu:

show history
show instrument/measurement/additional parameters
edit parameters

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.

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' pull down menu.

Instrument parameters: Measurement parameters:

INS - instrument type LWN - starting wavenumber

MAN - instrument manufacturer UWN - ending wavenumber

SRC - source setting WVS - wavenumber step

BSP - beamsplitter setting NOD - number of spectral data points

FIL - type of optical filter DAT - date of measurement

DET - type of detector TIM - time of measurement

VEL - scanner velocity PHC - phase correction mode

LAS - laser wavenumber PHR - phase resolution

AQM - acquisition mode PIP - phase interferogram points

SNG - signal gain ZFF - zero filling factor

RES - nominal resolution

Additional data acquisition parameters: APO - apodization function

APT - aperture size (mkm)

TOS - type of spectra STX - step in x dimension (µm)

NOS - number of scans STY - step in y dimension (µm)

XDI - number of pixel in x-direction

YDI - number of pixel in y-direction

SZX - area size in x dimension (µm)

SZY - area size in y dimension (µm)

SAM - sample name

SAF - sample form

OPN - operator name

AS1 - additional sample information 1

AS2 - additional sample information 2

AS3 - additional sample information 3

Parameters highlighted by red color should be carefully modified since these parameters are used by the 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 the faulty parameters (see command window below).
