Dear Mark
I want to ask for further question, can we calculate displacement distance of individual vertex data which derived from --savevertices flag ? For example,firstly, i performed the vertex analysis in hippocampus of Alzheimer's disease patient and normal control. In this analysis, i identified some vertices with significant shape change between two groups. After this vertex based analysis, I want to extract these significant difference vertices into correlation analysis to investigate the relationship between clinical evaluations and geometry properties. I think the displacement distance from mean surface (or model surface which available in FSL) may be a good indicator for such kind of investigation, could you give me some comments about which FSL commands can we use in this purpose ?
Best
