A software for membrane analysis and subtraction in cryo-EM.

This software utilizes 2D averages and their corresponding alignment information, employing methods such as Radon transform, cross-correlation, L1 norm, Bezier curves, Monte Carlo simulations, and Genetic Algorithm. It analyzes and subtracts membranes of any shape in cryo-EM, ultimately producing particle stacks and micrographs with membrane signals removed, which are suitable for subsequent membrane protein analysis.

• Capable of analyzing biological membranes of any shape, including simple lines and arcs, as well as more complex shapes like S or W curves;
• Accurately locates and subtracts biological membrane signals;
• Utilizes GPU and CUDA acceleration to enhance computational speed;
• Features a user-friendly GUI for ease of use.

• This software requires a GPU and CUDA acceleration. So, the installation of CUDA drivers and libraries is necessary.
• pyem is also needed to convert cryoSPARC’s .cs files to Relion’s .star format for processing.
