Please provide a few more details. Does the code throw an error, or harmonized populations are not adequate?

The harmonised populations stay separated. There is no error message.
Should the tumor cells merge?
What about the rest of cell types, are these separated?
Can you share the objective function plot?
Have you tried higher values of theta?

I am unsure if cancer cells from tissue and cell culture should merge. That is a tough biological question. I have not seen anyone else with the same kind of paired data. Is there such a data set within Broad Institute which you could try? I can't share the one which I am working on. Cell culuture contains only two cell types; cancer and cancer-associated fibroblast. Tissue contains eight cell types. Wouldn't lower values of theta
be recommended? I want the data to merge more, not less. I tried 0.
Can you share UMAPs before and after the integration of the two datasets? Also, theta needs to be increased to force the cells together. Setting it to zero disables the low batch diversity penalty.
Ah, O.K. increasing theta
is the solution which leads to good mixing.
