//a not working

Hi,
I am a newbie to NCover..
I used the following command to do coverage analysis..

C:\Program Files\NCover> ncover.console "C:\Program Files\NUnit 2.4.1\bin\nunit-console.exe" "E:\WD\UnitCheck.exe" //w "E:\WD" //a "Unit1,Unit2"

From this command i got the coverage for UnitCheck.exe application, but the Unit1 and Unit2 assembies not included in the coverage . Is this a correct method to execute..
Can you say the use //a with some examples..

Please help me to solve this problem..

Advance Thanks..
