there are 10 blocks numbering from 1 to 10 accordingly. I would like to get the frequency response plot to blocks from number 4 to number 7. the linear analysis points were set. when I perform the linearize(model), the error happended for block 2. I thought the block 2 is not my concern because i only want to perform frequency response for block 4 to 7. For this situation, how to deal with it?

1. Do it must require all the blocks need to be linearized?

2. Assume some blocks can't do linearize, then if I can say it don't get the bodeplot by the founction of 'control design->linear analysis' or not?

I hope someone can give me some guidance or suggestions?
