2023-04-03 From middle 2022, QtiSAS code has been supported by Konstantin Kholostov from JCNS instrument software team.

Code modernisation, optimisation, preparation for long-term-support is aim of the first steps of Konstantin in the qtisas project.

First code “surviving” steps:

• Git repository (iffgit) … done … link: https://iffgit.fz-juelich.de/kholostov/qtisas
• qmake → cmake … done … cmake >=3.24
• optimisation of compilation of 3rdparty libraries … done
• Python3 support (additionally to python2.7) … done
• “pure” QT4: removing qt3support dependencies … in progress … time-consuming step …
• “pure” QT4 → via QT5 → QT6: direction to newest QT … in plan …
• “Native” compilers @ Windows and MacOS … in plan …

Currently code could be downloaded from the repository and compiled like below:

git clone https://iffgit.fz-juelich.de/kholostov/qtisas
cd qtisas
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DWITH_PYTHON=ON
make

Current QT is still QT4, therefore “native” Linux system for the code test is used Ubuntu 18.04. Before starting above shown compilation, next stuff should be installed:

sudo apt install python3-dev pyqt4-dev-tools python3-pyqt4 python3-sip-dev

QtiSAS

• Project Explorer is working faster in case of many windows
• Plotting of a new Color Fill or 2D-plot will be filled full available space
• Several technical improvements were done…

DAN.SANS.

• We are ready for the future format of KWS-instruments: YAML header and Binary Zipped detector image
• YAML header added possibility to read 3rd and 4th levels in format YAML::NodeType::Sequence (detector duration time, monitors)
• YAML header example of header-reader string to extract detector duration: measurement:detectors:type|position_sensitive_detector|results|timer
• Zipped Binary Image currently at all KWS-instruments (new format) detector image is zipped binary array (*.array.gz). Reading and adding of zipped binary filed is implemented in the standard mode (single detector image). RT and TOF mode will be implemented later (should be faster adding and splitting).
• Zipped Binary Image many thanks to George B. for correcting of the reading function of Zipped Binary Images
• KWS3-2021 and KWS3-VHRD-2021 new standard instruments for data reduction of KWS-3 data with new YAML-format and Zipped Binary Images. Old data could be treated with “KWS3-2020” and “KWS3-VHRD-2020” instruments
• KWS-1 and KWS-2 current YAML header do not yet contains all motors values (like CA and SA); next version of QtiSAS will contain “KWS1-2021”, “KWS2-20%-2021”,“KWS2-10%-2021”, “KWS2-20%-2021”, “KWS2-HRD-2021”
• Data Processing Tab a bit modified optically
• Data processing is running faster and without fast changing of the windows.

2021-03-19 New Sasview Functions Implementation
Sasview Function Example (core-multi-shell), Sasview: rmsa

2021-03-18 New Introduction: Reduction of KWS-3 data: KWS-3@Data-Reduction-Example

2021-03-11 New Introduction: Reduction of KWS-1 data: KWS-1@Data-Reduction-Example

2021-03-11 New Version is online: downloads

DAN.SANS:

• Tr(EC-to-EB): now after changing of Tr(EC-to-EB) value of Absolute Factor automatically re-calculated
• Transmission-Method “λ<9.5A: ROI in Header; λ>=9.5A: Direct Beam [dead-time +]” works now correctly (KWS1-2020)

Fit.Curve(s): few optical improvements…

2021-03-10 Updated Introduction: Compile Fortran Code: Fortran Functions (linking with c++ functions)

2021-03-01 New Introduction: Simply-Fit (Standard Mode) of Fit.Curve(s) interface: Fit.Curve(s) Introduction

2021-02-26 New Introduction: Fit.Compile interface: Fit.Compile

2021-02-25 New Introduction: easy-Fit (“eFit”) mode of Fit.Curve(s) interface: eFit

2020-10 New: Unicode symbol in Legends:
Unicode-in-Labels

2020-07 New Version is online: QtiSAS:News:2020-07-06:

2020-05-04 QtiSAS Source Online: QtiSAS Open Source: 2020-05-04

As well as compilation of program from source is simplified to two steps:

1. qmake (withouth Python support, or “qmake py=yes” with Python )
2. make

All nesessary non-Qt libraries will be compiled in first step, and Qt-related during second one.

2020-04-23 QtiSAS:

• improved File|Export|ExportASCII… interface;

QtiSAS:Windows:installation:

• changed path to qtisas.zip file;

QtiSAS:HomePage news:

• started FAQs page with feed back option;
• few answers about export of ascii files are placed:
• faqs-export-ascii.pdf;
• dan-faqs-export-ascii-files.pdf.

2020-04-15

QtiSAS:

• if vertical resolution of display below 1000: log-viewer and project explorer are placed by default right;
• else: log-viewer and project explorer are placed by default down;

DAN@QtiSAS: v.2.2

• crash during opening of empty files in INFO-TABLE interface is finally solved;
• few cosmetic improvements are done;

qtisas-2020-04-15-info.pdf

2020-04-06 2D plot: new option is implemented:'Save Graph as Project + PDF-image’

• sans data-reduction projects are normally huge: sometimes containing hundreds of tables, figures, matrixes;
• new option extracts a selected plot with one or more graphs to new QTI-project and creates PDF-image of it (PDF-file is vector-image);
• this is an attempt to implement a kind of OLE object: PDF-file could be inserted to a PowerPoint presentation or Word-file; and in QTI-project could selected datasets could be quickly modified, analyzed, and plotted back to a presentation.

qtisas-2020-04-06-info.pdf

2020-03-25 DAN@QtiSAS New Version with improved stability ( v.2.0)

• crush during reading of an empty header is solved
• merging interface is integrated to DAN ( in qtikws merging interface was in DANP )
• 'Overlap control' option = 30% integrated to default KWS-instruments …
• newest SANS instruments are integrated as default options: KWS1-2020, KWS3-2020, KWS3-VHRD-2020
• mixed transmision option is integraded: λ<9.5Å: ROI in Header; λ>=9.5Å: Direct Beam [dead-time +]
