    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
    curvature-based registration.

    usage: svreg_label_surf_hemi.sh [subject fileprefix] [atlas fileprefix]
    [hemi] [flags]

    required input:
    subject fileprefix path and filename prefix of the subject’s output
    from BrainSuite’s Cortical Surface Extraction
    Sequence
    atlas fileprefix path and filename prefix of atlas files and labels
    to which the subject will be registered
    hemi the hemisphere to refine; either left or right

    optional flags:
    -v# Controls the verbosity of output messages (# is 0, 1, or 2)
    -t display timestamps along with output messages

    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.
    Error using readdfs (line 61)

    Error in surf_flatten_newbs (line 32)

    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!!!
