Error in GDFMesh while reading Wamit's demo testruns .gdf files

I am running GDFMesh using shell script, where -f is filename, -t is translations -g is Gravity Center and -p ... This GDFMesh.py is calling matlab engine to execute GDFMesh.m file..

python GDFMesh.py -f 'testruns/test01.gdf' -t 0 -g [0,0,0] -p 0

The first five lines of .gdf file is following :
TEST01.GDF -- circular cylinder, R=1, T=0.5, ILOWHI=0
1.000000 9.806650 ULEN, GRAV
1 1 ISX, ISY
256 NEQN
0.0000000E+00 0.0000000E+00 -0.5000000

I am getting error : Index Exceed Matrix Dimensions
NPAN(1,1) = header_a4(2,1);
