Hi,
I discovered this issue when debugging the way EVIO was written by the DAQ.. If I remember correctly, there're no option to use when you open the evio file, i.e. the "map" is there by default. I tried to change the jevio library, so that the error reported when opening a non-closed file is not thrown, but then I got bunch of other problems..

evio2xml should work.
The problem (at least, what I understood), is that the java evio library, when opening a file, tries to "map" the position of each event in the file. However, when the file is not completely written, this mapping presents some errors..

Are you able to read these via evio2xml utility from the C code?  Or load them with the C++ interface?

It seems to me there is something basically wrong with this data which is not an issue with HPS Java...

Hi,
when trying to run EvioToLcio on an EVIO file currently being written, I always get this error.

I’ve attached the simple script I use to run it …maybe I screwed something up there…
