External Email - Use Caution        

Dear all,

How can I easily scale the mgx.ctxgm.nii.gz files with the whole brain mean intensity using PETSufer? Is there a command to use in mri_gtmpvc like --rescale X? 

I know that I can find the mean in  global.gm.dat and I can use that value for scaling the atlas based results in gtm.stats.dat but how can I easily scale the image?

Thanks, 

Boris
