Yes indeed that's what appears.  Thanks for hints on mpiblast -- but 
the mpiblast.sh script works fine on its own.  I manually checked 
folders, permissions, ssh, etc on all suspected directives and 
everything appears fine as before.  As a matter of fact there are 
more than 10 similar files in the same location that got copied over,
no problem, so it appears "weird".

That's why I ask here -- (my first 3 lines in the post) -- any possible
known conflict when a working script and working qsub put together?

Thanks,
Zhiliang
