With ss2sf, you can provide a cell array of subsystem paths and the function will replace the specified subsystems with their s-function equivalents.

This works fine when you don't use busses. When a bus is used you can get error messages like this:
'model/subsystem' must be connected to a Bus Creator, Bus Selector or a block that outputs a bus using a bus object. It can also be connected to bus capable blocks that meet the conditions for supporting buses provided the bus entering the block has been created by using a bus creator.

The internal S-Function Generator works somehow different. It seems to split the bus signals into single signals. An information how that works would be appreciated.
