Hi everyone,
I've recently encountered a problem where VMD will crash when loading a rather large trajectory file (.xyz format, 700 MB, 44 atoms, 293360 frames). The error message is attached at the end of this email. This happens on a new Mac laptop that I recently purchased with 16 GB of memory with no other programs running.
I'm puzzled because my previous Mac laptop with 8 GB of memory was able to load a trajectory of this size with no issues. The "activity monitor" reports a small amount of memory used (about 1 GB allocated to VMD) when this crash occurs. I confirmed this error still happens with VMD 1.9.1, which is the version I had on my previous laptop.
If anyone could help me troubleshoot, I'd greatly appreciate it.
Thanks a lot,
- Lee-Ping
