Dear yt users, I am writing to you to know if somebody is using the sunrise_exporter to convert ART or RAMSES snapshots to sunrise. I have tried to update it but I found a problem I have not been able to solve by now. The problem is that sunrise_exporter needs of a "index.grids" object that is not defined in the ART or RAMSES frontends. It is defined in the enzo and ytdata frontends but I have not succedeed on exporting it to ART or RAMSES. Has somebody tried it? I would really appreciate any help you can provide me. Have a nice weekend. Best regrads.
