Narrative:
Clearance read 'at anc 11 DME turn to intercept bgq 145 degree radial.' if controller specified left or right, we missed it. We assumed and made a right turn as was customary for our direction of flight and tracked outbound from bgq. As we found out from the center controller, we should have turned left to track inbound to bgq.
