Creating the rd.dat for cl_merge - "too dense for [CR]sparseMatrix; would have more than 2^31-1 nonzero entries"

[JordanWean]

I am running a somewhat large dataset (17K x 110K) and wanted to use the cl_merge function but my transposed matrix has too many nonzero entities. I'm sure plenty of people have run larger datasets through this system so I'm unsure of what is wrong here. My norm.dat matrix has 458M non-zero entities and there are about 8K marker genes in my iterated clusters object.
