I’m having trouble getting a histogram from an existing file. Files attached. Running ROOT 5.34.00 on Windows 7.
I keep trying a few work arounds, but each execution fails with one of two errors:
root [0] .X viewspectra.C
--> Reading bin edges :
Check Number of Resonances: 67
Root File name: Mo97_2010_10ns_820_920_120keV_resonances_BGm.root

I’ve tried using both full paths to the histogram and using directory navigation…oddly enough with a cd() to the directory name and then gDirectory->ls() I can see all the correct TKeys. I’ve also tried accessing different histograms, with the same errors. As far as I can tell, my sprintf() statements are producing the correct file and histogram names. Any help or suggestions would be appreciated.
