I tried to overlay .w file onto a surface, and failed. I dug the previous posts and know this file format is obsolete now. However I wish to know in which version of freeview can I still use this file format, if possible. It will be great if you can provide the link for it. If this is not possible, is there a matlab tool similar to 'write_file.m' so I can output my data in matlab to the newer format (substitution of w-file)?

   Thanks in advance.

best
