Estimating the number of genomes in a metagenome

Question

[pfchuckran]

I am trying to determine how many genomes are represented in a set of metagenomic contigs. This is something I know is often estimated with short reads (such as with MicrobeCensus) or MAGs (CheckM), but I'm wondering if anyone knows of a tool to do this with unbinned assembled contigs. Don't care too much about phylogeny, just looking for an estimate of the # of genomes in my set of contigs. Thanks is advance!
