External Email - Use Caution Hi, I’m not an expert but since your question hasn’t been answered yet I thought I’d share how I’d do that. But as I’m not an expert this might be a wrong way. Please verify the following first. For example to go from [0, 110] to [-1, 1] you’d need a conversion like target_intensity = (2/110) * source_intensity - 1 I think that can be done by the following procedure. 1. You multiply every voxel (not just WM) of the original mri by 2/110 using mri_concat --mul (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/mri_concat) 2. You add -1 to the result of 1 using mri_concat --add 3. You prepare a mask image (=M) of the white matter using mri_binarize (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/mri_binarize). 4. You mask the result of 2 with M as the mask using mri_mask (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/mri_mask) Hope this helps.
