Hi, If you haven't done so already, I would ask this question on the AFNI help list. All the best, Mark On 27 Aug 2014, at 02:15, Mahsa Alizade shalchy <[log in to unmask]<mailto:[log in to unmask]>> wrote: Dear all Hi First of all please accept my apology for asking a afni related question but I'm extremely in need of help. Secondly I would like to render my structural brain image which is registered to MNI (i.e "st+orig.HEAD,st+orig.BREAK" in "/root/Desktop " ) and get a 3D image. As far as I know I should proceed as "Define Datamode ---> Plugins ---> Render [new]" . However,I could not load my image in "choose underlay dataset" and face "didnt find any data set to render". What should I do as the next step? Many thanks in advance. Best, Mahsa
