imperfection included in an analysis

Hello all,
 
I've been doing some search for a couple of days in documentation, but I 
haven't found any example that suits my needs. 
I am a kind on newbie in Abaqus.
I am interested in plotting the force vs displacement and the deflected shape 
under a certain load - for a simple model, which is a simply suported 
beam-column. I study he problem under large displacements. I've been using so 
far NLG udner a STATIC GENERAL case, without any imperfection included. I got 
the plot I wanted. The results seem to be feasible.
But I want now to introduce the imperfection from a *BUCKLE analysis, continue 
the analysis (within another step) with a RIKS under NLG, and then RESTART with 
another step to get the deflected shape udner a certain load.
The issue here regards the manipulation of these steps, and I wasn't able to do 
it properly.
 
Does anyone have a template with this one? I guess using CAE is straightforward 
 to generate the input file.
 
Regards,
 
Narcis
