Hello there people of Root,
I’m trying to use the “RECREATE” option on a TFile that already exists. As documentation says:
If dirname does not exist, it is created (like in “new”). If dirname already exist, all existing files in dirname are deleted before creating the new files.
I’m creating a TFile for which I keep changing the code and I want to run it over and over again for some tests and it’s really irritating that I have to delete the rootfile manually everytime before I can run the script again. This is the error:
SysError in <TFile::TFile>: could not delete SM1_20MNMMMS100008_FROM_2019_07_15_17_30_00_TO_2019_07_16_16_18_57.root (errno: 13) (Permission denied)
I also tried running root as an administrator but with no luck.
Extra information:
- The rootfile has directories and tgraphs stored inside
- Im using root 5.34/36 on windows 10
- I run: TFile* plotfile = new TFile((data_timestamp + “.root”).c_str(), “RECREATE”);
Thanks in advance, I’m really baffled as to what is happening
