I'm using 6.1.7 cadence and I completed the layout of my design.
I have done DRC and lvs analyze without error but when I want to do pex analyze, after I did the calibre view setup I got this message that I don't know what should I do.
My guess would be, you need a cell-mapping file used by PEX for "calibre" view generation.
It should be in your PDK directory under Calibre rule-decks... try to search for "calview.cellmap" file. That's how it is called in my case...
