Too large a percentage of total singular values #2

Closed ViriatoII closed 2 years ago

ViriatoII commented 2 years ago

Hi,

I get this message:

Warning in irlba(A = t(x = object), nv = npcs, ...) : You're computing too large a percentage of total singular values, use a standard svd instead. Error in checkForRemoteErrors(val) : 3 nodes produced errors; first error: more cluster centers than distinct data points.

Does scMagic not like my data? I only have 100 genes, is that the problem?

Kind regards, Ricardo

The gene number may be too small. In general, a single cell RNA-seq matrix contains at least thousands of genes.
