Question on error reporting

ROOT
1

Dear Rooters,

Recently I found these two error messages occur when I read some problematic root files (D3PD):

  1. file probably overwritten: stopping reporting error messages

  2. R__unzip: error in header

These two errors will not lead to abortion of the process. But I am still curious about which kind of problems would lead to those error messages. Thank you.

Cheers,

Hongtao

Hi,

In most case, it means that the data (that used to be on the file) is not available and your result will not be 100% accurate unless you do not need the information in the affected branches.

Cheers,
