[MITgcm-support] Query regarding overlapping in output files

*Hello MITgcm users, *

*I am a new user to MITgcm.*

*I am trying to configure MITgcm for observing Internal waves
propagation for my region (Bay of Bengal,Indian Ocean).
Initially, my input files are (a) bathymetry (360*270 matrix)(b) 3
levels temperature file (c) Wind files.
My /input/data file looks like :
====================
# | Model parameters |
# ====================
#
# Continuous equation parameters
 &PARM01
 tRef= 26.29,24.29,22.29,
 sRef= 3*35.,
 viscAz=1.E-3,
 viscAh=1.E-2,
 no_slip_sides=.TRUE.,
 no_slip_bottom=.TRUE.,
 diffKhT=1.E-2,
 diffKzT=1.E-3,
 diffKhS=1.E-2,
 diffKzS=1.E-5,
 f0=0,
 beta=0,
 gravity=9.81,
 rigidLid=.FALSE.,
 implicitFreeSurface=.TRUE.,
 exactConserv=.TRUE.,
 eosType='LINEAR',
 hFacMin=0.2,
 nonHydrostatic=.FALSE.,
 readBinaryPrec=64,
 writeBinaryPrec=64,
 globalFiles=.TRUE.,
 &

# Elliptic solver parameters
 &PARM02
 cg2dMaxIters=1000,
 cg2dTargetResidual=1.E-13,
 cg3dMaxIters=50,
 cg3dTargetResidual=1.E-13,
 &

# Time stepping parameters
 &PARM03
startTime=0,
 endTime=1080,
 deltaTmom=10,
 deltaTtracer=10,
 abEps=0.02,
 pChkptFreq=4000000.0,
 chkptFreq=0.0,
 dumpFreq=20,
 monitorFreq=20,
 &

# Gridding parameters
 &PARM04
 usingCartesianGrid=.TRUE.,
 usingSphericalPolarGrid=.FALSE.,
 dXspacing=3600,
 dYspacing=3600,
 delZ=3*50,
 &

# Input datasets
 &PARM05
 bathyFile='bathyBOB.bin',
 hydrogThetaFile='temBOB3lvl.bin',
 zonalWindFile='WINuBOB.bin',
 meridWindFile='WINvBOB.bin',
 checkIniTemp=.false.,
 &

My query is: the output depth files (Depth.data and Depth.meta) plots
is seen different to that of input bathymetry
file(bathyBOB.bin,bathy2DIM.txt). I am confused
: Is the model overwritting/overlapping the output file or anything
else......?????? Do help.

The images of model output and input bathymetry is in the attached tar
file (himansu_project.tar.gz). The other required informations ( code
and input directory)
is also in the tar file.

Thanking you in advance
