Dear Community, I use OpenEP to analyse Carto data, but I have a problem with Carto version. As you reported in your article, OpenEP works with Carto V6 version. Unfortunately, we have v7 version and this is a problem for the userdata. It is possible to create userdata structure using importcarto\_mem.m, but in v7 userdata.surface.uni\_imp\_frc and userdata.surface.act\_bip are empty matrix. This happens because in .mesh file ‘VerticesColorsSections’ and following rows are not present This is a problem for us, because it is not possible to create the 3D representation of the right ventricle values in the interpolated mesh. We are wondering if you and your team are aware of this problem and you are working to solve it. Any idea? ---

Hi Sorry for the slow reply. It’s a known issue I’m afraid and hopefully it will be adjusted in a future version. For now our approach is to use OpenEP to analyse the egms themselves. For this there is `generateInterpData.m` However we think the logic in this can be improved and if you check out the `feature/conduction_velocity` branch there are some new interpolators in there. Hope that helps? Steven
