Helical Processing using EMPIAR-10031 (MAVS)

Hi all,

I have been trying to import movies for the Helical processing tutorial using EMPIAR-10031 (MAVS) but it looks like cryosparc cannot read the gain reference files. I keep getting the error, ValueError: Could not read mrc data.
Has anyone had any luck importing these movies, and if yes, can you direct me on how to go about importing the movies? Thanks.

Best,
Prince.
