Is it possible to make gif with transparent background?

Is is possible to make an animation, i.e. rotating 3D molecule, export it to gif, preferably with the transparent background using Marvin?

Hello Anastasia,

Thank you for your suggestion. Unfortunately though, we do not support the export to gif at this time. 

Best regards,
