ROOT Version: 6.19.02
Platform: Windows 10
Compiler: Virtual Studio 2019
Trying to merge to root analysis files using hadd but when I do I am getting the following error.
I’ve double checked for mistakes in the file name and path so I’m pretty certain I’ve got that right, and I can’t think of any other reason I’d be getting this error. Any help would be much appreciated.
I can’t reproduce the problem with ROOT master:
C:\Users\bellenot\build\release\bin>hadd C:\Users\bellenot\Temp\test_hadd.root C:\Users\bellenot\build\release\tutorials\hsimple-test.12345-10 C:\Users\bellenot\build\debug\tutorials\hsimple-test.12345-09
Warning in <TClassTable::Add>: class ROOT::Detail::TTypedIter<class TEnumConstant> already in TClassTable
hadd Target file: C:\Users\bellenot\Temp\test_hadd.root
hadd compression setting for all output: 1
hadd Source file 1: C:\Users\bellenot\build\release\tutorials\hsimple-test.12345-10
hadd Source file 2: C:\Users\bellenot\build\debug\tutorials\hsimple-test.12345-09
hadd Target path: C:\Users\bellenot\Temp\test_hadd.root:/
Can you try to open the file in a ROOT session?
And from the ROOT prompt, with
Oh, I’m running hadd in one folder and the files are located in another. Do I need to place them in the same folder?
Nope. Just check the example I posted before…
I can’t seem to find it, can you link me or give me the name of the post? Thanks for the help
Well, that was an example with the regular
hsimple.root files that I renamed to match (more or less) your file names…
Oh sorry you meant as part of this thread. I thought you were referring to another post you had made. Thanks I’ll try that
And did you manage to open the file in the ROOT command prompt?
No, I think I might be using TFile::Open() incorrectly, I’m pretty new to ROOT. This is the error I’m getting
You forgot the quotes (it is a string), and please try with the full path. Something like:
auto f = TFile::Open("C:\\Users\\Stephen\\root_v6.19.02\\test\\GetDetector-60Co1.3325MeV-50000")
auto f = TFile::Open("C:/Users/Stephen/root_v6.19.02/test/GetDetector-60Co1.3325MeV-50000")
Ah of course. when I run root in the test folder it opens no problem, but running root in the bin folder where hadd is I’m still getting the error that the file does not exist
And you have the error with both backslashes
\\ and forward slashes
Hadn’t tried \ \ , one minute
Wait works with / / just needed to include .root extension
hadd is working now using those file paths. Thank you very much, really appreciate it!
Oh yes, indeed, the file extension is needed…
