Hypermesh to Msc.nastran

Hi all,
 

I am a fresher and so struggling with Hypermesh(HM)
 

I want to use HM as my preprocessor(with Nastran profile) and Msc.Nastran as solver. However, I feel load steps and load collectors do not get converted when I import .bdf .
From google, I found that we need to input some data in .bdf before running in Nastran. However, I am not able to understand what to enter for a particular analysis type.
I am trying modal analysis and FRF.
