Dear Expert,

I have a geant4 results in root format.
The simulations is finish as normal but don’t know why the output could not open.
It show the message “Error in TFile::Init: file Output_t0.root has an incorrect header length (206) or incorrect end of file length (188)
(TFile *) 0x5574d713a9e0”

I have try to write TFile::Recover and TFile::Write in new TBrowser’s command line but the file still could not open.

I’d appreciate any help on this.

Best,
Arif

Dear Lorenzo,

Thank you so much for your reply.
I have tried to upload my root file in here but it exceeds the size (<3 MB)

Cheers,

It looks like the file was not properly written. Most likely a final call to file->Write(); in the writing app (i.e. the Geant4 simulation).

Hi @pcanal

Thank you so much for answer.
Is there any way to recover this corrupted file?

Best regards,
