The project developed a correlative light and electron microscopy (CLEM) workflow for ultrastructural mapping of protein distributions in cells. It aligns high-resolution TEM images with fluorescence microscopy channels using fiducial markers. LM provides multi-channel protein labeling through fluorescence microscopy, while EM offers nanoscale morphological details. Aligning these images enables comprehensive insights into cellular structures. Key aspects of the image analysis pipeline include:
• Fiducial particles detection in EM images using the template matching algorithm
• Fiducial particles detection in LM images using the Big-FISH Python package
• Finding correlation between EM and LM images using the Coherent Point Drift (CPD) registration
