Hello, 

I guess this is not exactly the purpose of VMD, but we try to visualise an Atom Probe Dataset which we converted to *.xyz Format. The dataset consists of 6 million atoms and at least the Mac OS X Version of VMD crashed when trying to load the data, while loading a subset of the file worked fine. 
The question is whether we can compile VMD with special packages to support such large datasets or whether other file formats are more suitable for loading such large datasets. The file size is currently about 2GB. 

Regards 

Jan
