  I have been trying to draw my protein and several of its residues using surface representation 'SURF' but for some reason it displays only a small portion as surf not the whole protein. The following commands are executed in vmd console:

vmd > Reading 4716 atoms..done
Probe radius = 1.400
Constructing solvent-accessible surface ..
Max edge length = 1.200
Malloc of zero or illegal length!!
length = 0
Malloc of zero or illegal length!!
length = 0
...........compute_tri_plane_int(): denom close to zero 0.000000
Total Triangles 255214 Total constraints 228706
Max Neighbors per atom 90 Average Neighbors per atom 48.4958
Surface construction + writing time 4.94 seconds
Info) This surface is made with SURF from UNC-Chapel Hill. The reference is:
