Dear Prof.Gale,
Could you please suggest me visualization softwares for GULP apart from OVITO and GDIS.
My output file is not getting supported in OVITO. GDIS makes it very difficult to name the atoms nor count it.
The best visualisation software for GULP is obviously Materials Studio. See the Biovia website for more details on how to obtain a license.
Alternatively, if you’re trying to do things for free then you’ll have to stick with OVITO or GDis.
If your output format is not supported in OVITO then you can always get GULP to output a different file format that is supported (compare OVITO and GULP documentation to find one that’s common to both). GDis supports names that GULP accepts, so it’s hard to know what the issue is there.
