Related algorithms are included in SPM2, but segmentation in SPM2 does not include a number of the features that are found in EMS. These include: * The use of MRFs to improve segmentation accuracy. * Automatically segmenting lesions from multi-spectral data. Segmentation in SPM5b will do some things that EMS does not, but it still won't cope with lesions or use MRFs. Best regards, -John
