Hi again,<div><br></div><div>OK. I managed to reverse engineer things back from mri_tessalate.c</div><div>Here is the code snippet that should be added to read_surf to parse these new files:</div><div>NEW_QUAD_FILE_MAGIC_NUMBER =16777213;</div>

<div><br></div><div><div>elseif (magic == NEW_QUAD_FILE_MAGIC_NUMBER)</div></div><div>  vnum = fread3(fid);</div><div><div>  fnum = fread3(fid);</div><div>  vertex_coords = fread(fid, vnum*3, &#39;float32&#39;) ; </div><div>

  tmp = fread(fid, fnum*3*3, &#39;uchar&#39;) ;</div><div>  tmp = reshape(tmp, 3, 3, fnum) ;</div><div>  faces = reshape(bitshift(tmp(1,:,:), 16) + bitshift(tmp(2,:,:),8) + tmp(3,:,:),3, fnum)&#39;;</div></div><div>end</div>
