Thanks @ali.h! Yep, both jobs seem to start when using a mask imported directly, testing now! And yep, I think both mask creation and the way mask “blobs” from refinement jobs are handled need a look - it looks like for the mask is created by the volume tools job, but the mask “blob” doesn’t have a thumbnail of the mask and seems to contain zero objects. I wonder if the mask ism being created but not connected up somehow.
I actually used the mask_refine output of a regular refinement job, not a non-uniform refinement job, which caused the initial problem - both give the same issue.
Cheers
Oli
