The flowchart details the workflow for FSLFIRST segmentation of subcortical brain regions and post-segmentation processing. The process begins with MR Images. The next step is Registration to MNI152 template using Affine Registration. Following this is Subcortical Segmentation using FMRIB's FIRST. The subsequent step is the Generation of Subcortical Segmentation Masks. The final step is the Extraction of Segmented Structures through Bounding Box Cropping.Workflow detailing the FSL–FIRST segmentation of subcortical brain regions, followed by post-segmentation processing for extraction of the actual brain structures from binary masks, which FIRST generates
