deepprobe with analog extract

Hello, I'm using deepprobe in my simulation, but when replace the schematic view with analog extract it's stops working. For sim with schematic I use such syntax for access some net top_level.level1.level0.net_name In analog extract no hierarchy, and the same net is renamed to level1|level0|net_name I've put in the deeprobe properties top_level.level1|level0|net_name But simulation can't start because of the error " Unexpected operator "|" What syntax should I use in this case? Regards, Nikolay
