[ROOT] getting filenames from TChain

 We are chaining together 3 parallel sets of Root files; they are named like mc0nnn, digi0nnn, recon0nnn. In this case we have 200 files of each brand. We assumed they would be chained by wildcard in alphanumeric order, but for some reason the mc files are not, screwing up our synching of the files. We did check that the sum of events is the same in all three streams.

 

 I have not been able to figure out how to get at the list of filenames that TChain uses. How does one do that? Then I could verify the order we're seeing...

 

 Is it correct that the sorting is alphanumeric by filename?

 

Thanks,

 

Richard
