Question: Can DC1 be well correlated to PC1?

[katsikora]

Dear Devs,

I have applied destiny::DiffusionMap to one of our internal datasets, providing the Seurat "data" slot normalized in a standard way as input (log2 (normalized counts + pseudocount)).

When I plot DC1 against PC1 on this dataset, I obtain:

Does this say anything particular about the dataset?

Thanks in advance for any hints,

Best,
