Hi Amardeep,

Thanks for the format conversion and also for putting up your data. I was
able to reproduce the problem at my end. Your images had a negative origin
and revealed a bug in code. This has been corrected now in the latest CVS
repository.

Meanwhile, I have placed an example script and its output:
http://bmi.osu.edu/~kishore/Amardeep/

Please try it out at your end and let me know how things work out.

Kishore
