hilite_system inside a library block

I am trying to use hilite_system to hilite a simulink block, however that block lies inside a library block. If I open the model and make the call to hilite_system I get an error that the object name is invalid. However if I navigate throught the model into the library block and try again it works. It would appear that the problem is that the library block is not fully "loaded"? Is there a way around this?

It is true. When you open the model, Simulink doesn't automatically load all the customized library blocks.
To make your script work, I suggest adding a line after you open the model.
Open_system(Model); find_system(Model,'FollowLinks','On');

I already tried that, it didn't work either.

I wrote code to parse the path and call find_system on each block "leading" to the desired block before calling hilite_system and it is working great. Thanks for the help.

So you have a model with nested library links. I have a model with three layers of nested library links. The find_system() seems to work so I don't know why it didn't work in your case. I am using R2007b.
Try a different approach, run the command libinfo(Model) after opening the model. It works too in my case. If it works for you, it might be easier than parsing the block path.

libinfo is definitely simpler and does work, but parsing the string and calling find_system multiple times is definitely faster. Most likely because libinfo is loading every library that the model references not just the ones required for the current query. Thanks for the info, I will definitely file that one away in my "bag of tricks."
