Article GEO gives counts that are not integers. Should UMI counts be integers? I thought that UMI counts are always integers, but when I opened several datasets provided by GEO I got confused because in some articles they provide counts that are supposedly non-normalized raw UMI count values, but they are not integers. For instance: GSM2043231 or GSE77067

Could anyone clarify, what these people mean by abundance measurements?
The data processing section doesn't mention using UMIs at all, so it's likely there were none (whether they'll be present depends on how the libraries are made, with lower throughput methods being less likely to include them). The values are stated as being expected counts from RSEM, which is why they're not always integers.
