# Given a list of files and weights (cross sections)
|
| 4 |
# this will do a SetWeight() on a TTree in those files.
|

# Usage:
|
| 7 |
# setTreeWeights fileOfFilenames treeName
|
| 8 |
#
|
| 9 |
# The "fileOfFilenames" should have two colums.
|
| 10 |
# One column is the root file name, the other is the weight.
|
| 11 |
# Example:
|
| 12 |
# file01.root 105.2
|
| 13 |
# file02.root 92.0
|
| 14 |
# file03.root 11.0
