Dear McLaren Donald,
I've downloaded your peak_nii.m, yet not sure what to do with it in
script. Shall I simply add it in the path of Matlab and run 'peak'? It
seems dose not work.
Also I found you have a toolbox of 'OrthoView', which seems really
nice. It would be wonderful if you can put the peak.extraction
function in the GUI view of Orthoview.
Thank you very much!
Best regards,
Gao mmhjfhbvhgbfv gfgvc f
