When a mask is input from a parent refinement job, 3D-FSC gives the attached error.
Hi @olibclarke was this run by connecting the half-maps (volume input group) and then connecting a separate mask input group with the mask from the refinement job?
Or was this with the half-maps and mask in the volume input group, straight from the refinement job?
(If the second case, you may already have done this but you can work around by connecting any other mask input the the mask input slot of 3DFSC and then override the mask slot itself from the volume output of the refinement job)
The former - it was a mask input group, with only a single mask in the group, directly from a previous refinement.
If I manually re-import the mask, then it works.
