Dear Bruce and All,
In my *View--Configure*....there are three button which are activated
(*Light, caption and phase Encoded Dat Display*), without "*functional
overlay*" option.
And in these activated buttons: light(light 0,...,light 3, with the
value, 0.4, 0.0, 0.6, 0.2. and brightness: 0.35). In the option of *phase
Encoded Dat Display *(*Angle Cycles:1.0; Angle offset: 0.0*)
I just use *File--load overlay* then choose that **.volume* file to
show that volume. And in the terminal there are error information:Couldn't
load *.volume, Vset_read_vertex_set:MRISreadVertexposition failed.
Thanks a lot for your help!
Joe
