Sorry I ask this every time but what command updates the trunk?

Follow the links:

MAUS wiki > MAUS developer documentation > Contributing to MAUS > Branch merge procedure

What the error means is that one of your maps is failing to launch. It may be worthwhile starting just with MapCppSimulation in the list to make sure it's that one. I should probably add a check that prints out which map is failing.

So you have all the standard maps in there and the only thing you've touched is MapCppSimulation? What changes have been made to birth within that? Could geant4 be failing for some reason to load your geometry that MapCppSimulation catches?

I did the merge preview with lp:maus and it turns out there is a lot of changes which I don't have but there were also a couple of conflicts. So I thought I would just delete these couple of files and the merge will just replace them with the new ones and they didn't. I then revert back to the version before the merge to then do the merge properly and the merge command says 'nothing to do'. How can I merge the trunk now.

I think that the error is coming about because of the missing file from the trunk. (hopefully)

I have now updated the trunk and everything seems to be working :-) I have just tried simulating the CAD quad (after I noticed some errors in my conversion which have been corrected) and I am getting this error when I simulate

I will turn the verbose level to debug to see what it says and post it ....

verbose level 0 gives,

Something evil in a file io operation probably. Can you give me a copy of the input files so I can run it myself (say, attach to the issue).

Cheers...

Could you attach also simulate_for_matt.py?

Better also to make a tarball, like

tar -czf geometry.tgz TDm*.dat

and then upload geometry.tgz

I ran against the trunk and got something like:

Note the error message is different

ErrorHandler.CppError: Dimension x in module ParentGeometryFile-copy.dat/TDm1152m9315.dat0 out of range at MiceModToG4Solid::checkDim

so worrying that the errors aren't coming through correctly, but looks like bad user input.

Looking at the input file TDm1152m9315.dat, I also note that there is no closing brace.

Its odd that doesn't come up on my machine :-( but that is an error I've seen before so I know what that is ill fix it and see if I get the same error again
