pynida

This software allows one to perform a full cycle of in-situ nanoindentation data analysis, including the video processing

Current limitations:

• Only avi files for video
• Dark-field images are expected for the particle shape evolution analysis
• Magnification should not be shanged during the experiment

Installation

Requirements

matplotlib
numpy
opencv-python
pandas
PyQt5
scipy
>=scikit-image-0.18

Currently, to install the software one should install all the prerequisites, and to execute in the folder for choise the following commands:

$git init
$git pull https://github.com/LebedevV/pynida

Afterwards, to run it:

$python pynida

Feature requests and planned work

Known bugs

• fonts in GUI might be corrupted
• re-measuring of the rotation angle happens during the comparison stage. Might results in the wrong rotation angle in output
• (not related to the software itself) scales measured by the scalebar and by metadata may be different
• (to check) button "q" for exit from plt windows is not working on Ubuntu
• (to check) test imgs are saving nearby the opened file, not in the output dir

Planned work, long-term

• add dm3/dm3 import
• scale down preview (need in a lineEdit for that?)
• add "save video" option
• fully automatic scale detection. Will allow one to deal with the variable magnification
• for rotation: GUI with grid and drag&drop
• (?) Graphical scheme of indentation to GUI

Planned work, short-term

• check fps values in output files
• proper logs should be configured
• allow shape analysis for the BF-TEM
• (partially done) preview of areas/contours, in pix/fr
• Fix column names in output files
• (partially done) Add descriptions to output files
• (partially done) file format checks
• update pnm by units recall
• make code more readable, especially in the areas analysis
• (done) probe the write access to the output dir
• reduce number of global variables
• (almost done) move errors to qmesg
• same checks on different buttons - to unify
• video is probing every time in update_crop. To replace with the affine transform
• create a list of failed frames for areas/contours
• add unit tests!
