Hello SPM'ers
I have 2 VBM5 related questions:
1) I used SPM5 for segmentation to created *sn*mat files for the Dartel to read. I then ran Dartel and using John's snippet converted the images from Dartel to MNI space. I had ran the VBM using optimized VBM2 (SPM2) and I could add Total Grey Volume as a covariate in ,y analyses. How can I get this information from SPM5 segmentation and Dartel normalization? Can I use the volume results from VBM5 script in my group analyses for the images generated by DARTEL?
2) How can I calculate volume differences for specific regions? Lets say I see difference in amydgala in the whole brain analyses. Can I get the exact volume (value) that differs? Also, is there any kind of ROI analyses for VBM wherein you can just look at certain regions specifically?
