Windows VMD is a 32bit application. If you try to load a trajectory that
exceeds 4GB (or smaller in some conditions) VMD will fail.

 

You need to use a 64 bit version of VMD. At this point in time that would
have to be on Linux.

Subject: vmd-l: APPCRASH when loading a big trajectory file (.dcd) into VMD

 

Dear VMD users,

I have a problem that I have tried to figure out for quite some time but I
still can't find a solution for it. The problem is an APPCRASH issue when I
try to load a big trajectory file (.dcd) into VMD. I don't face any problem
when loading a smaller trajectory file with 1GB++ size. The problem occurs
when I try to load a >2GB trajectory file. I'm using VMD 1.9.2 Windows
OpenGL. There is a big physical memory in my computer, so this is not due to
the memory issue. I wonder whether it is due to the internal setting in VMD,
which prohibits files larger than 2GB.

 

Really looking forward to solve this problem. Any help is welcome.

 

Thank you.

 

Cheers,

Ernest
