Thank you very much.
Here is the output.
surface registration and labeling (svreg)
This is the main program for surface registration. First, the surface is
smoothed to create a multiresolution representation of the surface. An
initial registration is performed by aligning the 3D coordinates of this
smoothed surface. This is followed by p-harmonic mapping to a square and

Here is one of the errors i am getting from the run..
Using Executable /Applications/BrainSuite18a/svreg/bin/warp_points_mac
A matrix with a negative or zero determinant was encountered. (AIR_NON_POSITIVE_DETERMINANT_ERROR)
SVREG Warning: .warp file was not in correct format. Continuing after trying to fix.

another is the pial line. While brainsuite is running, i can see that it was too much inside the brain, sometimes including the inner temporal!!!
