iter_clust keeps failing

[deevdevil88]

Hi Im trying to run the scrattch.hicat module on some 10x data. however the iter_clust function keeps failing with the error Error in unique.default(cl) : unique() applies only to vectors

I am not sure what is causing this. It works fine on the toy dataset on tasic2016 data but seems to fail on mine. I am using log and not log2 normalised values which were first corrected for library size and then scaled to factor of 10,000 in seurat. Primarily because UMI counts are much lower so its common to use this than cpm or fpkm. can that be causing the error.
