Direct imperfection to Nodal coordinates in ABAQUS

Direct imperfection to Nodal coordinates in ABAQUS

(OP)
Hi friends,

I am trying to imperfect some nodes in my model by using *imperfection keyword with directly defining the imperfect coordinates in the edit keyword file. I'm getting an error '' node number must be positive integer'' however, I've given integer nos for the nodes. Does some one know the solution. I've gone through the abaqus manual, and also some relevant posts for this same roblem, but haven't found the exact solution.

Thanks in advance
