Re: Problem with merging trees via hadd

Hi Michaeal,

 > the files are stored on the lxplus machine 247 in the tmp dir: /tmp/boehlerm

However, I am unable to open the directory:

     scp: /tmp/boehlerm: Permission denied

 > I saw, that the highest cycle version differes from the file in output_0001 to output_0002 and output_0003.

That is controlled by the way the file were produce is usually directly related the amount of data in the (final version of) the TTree.

This is odd, I will need the files to try to reproduce this problem.

Cheers,
Philippe.
