[Wien] scp error

[Yundi Quan]

Dear Sir/Madam,
I am running WIEN2k on a cluster. I usually use 4 nodes with each node
having 8 cores and 8G memory. The queue system is torque.

 I first did the scf calculation to convergence. Then, I tried to
calculate the density of states. I used the following command:
x lapw2 -qtl -p -it.

Though I did not get any error message, I did find the following line
in my output file:

scp: .//case.vector_1: No such file or directory.

But case.vector_1 is in the current folder. What is the reason why I
got this message?

When I ssh to the nodes, echo $SCRATCH gives ./

Any help would be greatly appreciated.
