Q2- What I am getting is a top file but gro file processed with hdb and rtp gives a very weird structure which has nothing to do with PE chain.


Your central problem is that your C4 unit is not aligned with any axis, so replicating it straight along the x-axis won't work to generate the proper geometry. Use editconf -princ to align your structure with the x-axis, then do some simple geometry to figure out the proper value for -d to get the correct periodic spacing.

Thanks for your attention.
