The F8 key can be used to switch between perspective and orthographic projection viewing. Orthographic projection viewing should be used for looking at flat maps.

Spec files referring to flat maps should use embeddimension = 2, and embeddimension = 3 otherwise.

Suma can AFNI can sometimes stop communication with each other. You can try to restart communication by hitting the "t" key. The problem may also be fixed if you start suma with the following option:

 suma -ah localhost

or possibly

 suma -ah 127.0.0.1

Volume Rendering in SUMA

Volume rendering can be performed in SUMA as follows by simply creating a displayable objects file with the name of the anatomy that you want to load: e.g. /Volumes/data1/UT/HP/VolRend.niml.do

 <nido_head
 coord_type = "mobile"
 />
 <3DTex
filename = "HPanatavg+orig.BRIK"
overlay0 = "Balls+tlrc.BRIK"
 />

(The overlay is optional). Press Ctrl-Apple-S in SUMA and load the file.
