Visualizing ellipsoid in OVITO

Dear OVITO team,

I’m trying to visualize the LAMMPS data file which contains ellipsoid features with OVITO. When selecting the LAMMPS atom style as ellipsoid when opening the data file with OVITO, I got an error that :
" the atom style of the LAMMPS data file cannot be detected … " .

I would appreciate to help me with visualizing ellipsoid data file.

here is the header and the body of the data file :

LAMMPS Description

Hi, please excuse the late reply. While OVITO can load and visualize ellipsoid particles from LAMMPS dump files (see here), the support for the “ellipsoid” variant of the LAMMPS data file format may still be incomplete. We can work on completing the support for this type of files. It would be useful if you can provide your complete data file as an example. Thanks.


Dear Alex,
Thanks for the response. Yes I had no problem visualizing the ellipsoid from the LAMMPS dump file with OVITO, but the problem is visualizing the DATA file as well. I’m trying to upload the DATA file, but I got the error that “new users are not allowed to upload a file”!
How can I send you my DATA file?

Thank you in advance,
