Thanks for your kind reply.
I try as your suggestion, but still failed.
However, If I set the superlattice size is 8 A, the calculation can be carried out.
I will try to compile the vasp.5.2.2 again .

by the way, the kpoint was set to be Gamma.
CO was put into a 3D cube with the length of 1 nm.

Thanks for your kind reply.
I try as your suggestion and still failed.
I paste the output .
This is the CO vibration frequencies in the example of vasp.

Dear Prof Graeme,

I compile the vasp5.2.2 and vtstcode2.04b succesfully.
If I use it for geometric optimization, it works well. However,when I use it to calculated the IR vibration, it doesnot work if I dont set NPAR=1; and it just calculate the 1st value 1F=..... and stop if I set NPAR=1 in INCAR ...

Dear Professor:
I download the vtstcode, and replace the chain.F with the new one,and modify the corresponding contents of makefile as the suggestion in web(SOURCE=.....). Then I recompile the vasp makefile.
When I do a work , however, I find that something is wrong with my OSZICAR as following:
