Major pytraction update in April 2024

[nik-liegroup]

Changes

• General streamlining of traction force calculations
• Added option to use dynamic reference frame (bead displacements between time steps)
• Added option to use 3D image stacks for 2D traction calculations (plane selection or maximum projection)
• Added Boundary Element Method (optional) for solving inverse solution
• Updated PIV algorithm (widim function is no longer supported and does not work with newer numpy versions)
• h5 result files now include PIV, interpolated displacement and traction fields as well as drift corrected image stacks
• Revised plot function to support averaging over multiple images
• Added function to calculate strain energy density field and integral over ROI
• Option to create .gif movies from time series
• Fixed issues with outdated libraries during installation
• Fixed issue with incorrect scaling
• Added more example data
• Added more comments and detailed function headers

Thanks @nik-liegroup, I'll review at the weekend
