Hello,

Just to let you know that there’s a new version of SUMA with many new and at times useful features.

Major changes to the surface controller (View --> Surface Controller):
----------------------------------------------------------------------
Interactive color mapping
Threshold controls
Brightness modulation
Choice of color maps (including your own)
Coordinate bias (transforms surface data into relief: looks very cool)
Information on current cross-hair location

New programs:
-------------------
SurfPatch
Create surface patches from a set of nodes
SurfQual
Report defects in spherical surfaces
SurfSmooth
Smooth surface geometry (without shrinkage) or surface data
SurfMeasures
Output surface measurements such as thickness, area, volume, etc.
quickspec
Create a minimal spec file for one or a bunch of surfaces
FS_readannot
A program to read FreeSurfer’s surface annotation files into SUMA

New options to note:
--------------------------
in SUMA “Save View” and “Load View” to save and load viewer settings

in 3dVol2Surf -first_node and -last_node for controlling output file size

in ConvertSurface -xmat_1D for applying an affine transform to node coordinates

Documentation:
-------------------
The most up to date sources of documentation are the -help option for command line programs and ctrl+h and BHelp button for SUMA. Web site will be updated soon.

Binaries for AFNI and SUMA ver2.5 are available from AFNI’s website: [afni.nimh.nih.gov] . Binaries dated June 15, 2004 or later contain the new version.
