Hi Wilko, I changed that function in order to handle any checksum size. Unfortunately I am not able to find a server/file giving me any checksum. This is what I get from bbrprod01: 041118 06:15:44 001 Xrd: SendGenCommand Server declared error 3010:Check summing path '/kanga/prod/store/PRskims/R14/16.0.1a/AllEvents/23/AllEvents_2301.01.root' is disallowed. Please, can you tell me something I can checksum somewhere? I will commit the change when I am able to test it at least once. Differently from the former version, which I committed without any available server doing checksums at the time...
