It's a little late to change the default now to raising an error instead, but maybe we could add a warning?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,621078539

`BaseCounts_dim1` is length 4, so maybe that corresponds to DNA bases ATGC?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,621078539

For that reason, we really want all dimensions to always be named.

We could possibly add support for unnamed dimensions in the Dataset constructor, but on the other hand it also provides a gentle nudge to chose names.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,621078539
