[Gate-users] filemerger...

[Samuel BURG]

Dear MJ,

I have also lot of problems with gjm.
One 'easy' solution is to do a 'fast merge' with gjm and the to use a TChain under ROOT to post-process your (multiple files) data.

Pro : it works, no need to update any code
Cons : files 25% bigger, not very fun

Hope it will help you,

regards,

Samuel Burg

Dear Jan,

I attached a file with sample root, macro files and gjm also.

I tried with small root files...
[My real root files are over 600M]

It said a little bit different message...

Subject: [Gate-users] filemerger BUG

Hi,

I think I have found an error in the filemerger gjm:

In the method

bool GateMergeManager::MergeTree(string chainName){

in file src/GateMergeManager.cc I believe a 'return' is missing on line 467
which should IMHO look like this:

  if(chainName=="Gate") return MergeGate(chain);

Otherwise it will run into the error
"Cannot find one of: runID, eventID, time in Gate" (line 482)

Regards,
Hannes
--------------------------------

so I change the source as the mail said...
but, I still got this error message...
