Question Error message concerning unsupported layout ?
Diagnosis: You are running a job that aborts with the following WARNING:

IOVDbSvc                                INFO Resolved TagInfo tag GeoAtlas to value InDetLayerMat_v6_ATLAS-GEO-03-00-01
IOVDbSvc                               ERROR resolveHVSTag> tag: InDetLayerMat_v6_ATLAS-GEO-03-00-01 does NOT exist

Possible reasons and solutions:

1. The layout you've chosen does not exist !
Tip, idea Check the string with respect to the supported ATLAS layouts.

2. The layout exists, but has not been created as a tag in the conditions database for the TrackingGeometry.
Tip, idea Look for more detail here.

3. The navigator (a part of the extrapolation engine) tries to retrieve the TrackingGeometry before the geometry callback has triggered the building of the TrackingGeometry. This is a common problem seen when running on AODs.
Tip, idea Move the retrieval of the Extrapolator to the BeginOfRun method or.

Question I have problems to configure an Extrapolator AlgTool
Please have a look at the latest Tracking/TrkExtrapolation/TrkExExample/share/ for a valid setup.
