Release Note

MPicker version 1.2.0, 2025-2-13

Optimized the function for projection on elliptical cylinder. Set Project Order to -2 to force the use of circular cylinder (elliptical cylinder remains -1).
Surface ID can be shown when right-clicking on the "purple curves".
Added Mpicker_2dprojection_torch.py, the GPU version of Mpicker_2dprojection.py, which accelerates 2D particle extraction, especially for large sizes. It can also efficiently sum the sub-volume by setting --tomoout.
Added Mpicker_align_class2d.py to automatically align the result of Class2D.
Added Mpicker_prepare_rln2.py and Mpicker_prepare_rln4.py to further simplify the preparation of STA files (run after Mpicker_convert_class2d.py).
Fixed a bug where Euler angle conversion may be incorrect in some special cases.
Updated the Installation (for OptCuts) and Advanced Tutorial.
Updated the environment, added libraries igl and opt_einsum in env.yml and env_simple.yml, see Installation for details.
Fixed compatibility issues with higher versions of PyTorch (tested with PyTorch 1.13.1).
Other minor changes.
Fixed some bugs.

Added more functions in the GUI (such as Eraser, FlipZ, Screenshot...).
Sped up 3D display by using texture.
The surface in 3D mode can be exported as obj file (with texture).
Optimized the usage of EPicker in GUI.
Optimized the usage of Mpicker_epicker_batch.py.
Added Mpicker_convert_class2d.py to convert the result from Class2D (more powerful than Mpicker_convert_2dto3d.py).
Added more options in Mpicker_particles.py (such as output in star file format).
Added Mpicker_check.py as a standalone tool to open tomogram (same as the xyz mode in GUI).
Other minor changes.
Fixed some bugs.
