Re: [Brahms-dev-l] Acceptance maps

Hi,

so where is your problem, is it when you run the program generateMaps?
What is the error message?
Do you get a core dump?
Or is the result just strange? and if so relative to...???

I need more information.

I don't have any problems running the version in CVS now, and I use it
for run04, run05 and run06 62.4 GeV data...

You say you modified the code to include MrsT0. Did'nt this trigger
device cover the entire opening of TPM1?

Cheers,
	Truls
