performance analyzer

how can i remove system calls from the analyzer output and make it display only the relevant methods that i need. i'm attaching a process to the debugger , it loads all the .so files, then i say collect sample upon which it creates an experiment. but the anaylzer is giving too much info, more than what i require. i want to check on only some methods in some .so 's . is there a way to filter like this.
