Hi Djam You are certainly right that brag-1-1-12 used guxint 1.7 which had the PC changes overwritten. I will like Peter to comment specifically on the validity but I would guess the errors on the acceptance map is de facto larger since the additional files generated just adds to the 'same' content after a while - but this is probably NOT the dominating error in the analysis at this time (statistics, cuts, effeciencies.) > > This sounds not good at all.

I agree whole hartedly- this is also why the versioning and tagging of code + knowing what you used is paramount. As a second comment - Hiro was not to blame for the change in guxint.F - but someone else, in any case for all please recall the lesson.
