error: no duplicates allowed in deviationsTsne

[o-doyle]

Hello,
I am trying to generate a Tsne plot to look at the distribution of different TFs between clusters as in the chromVAR vignette. However, whenever I run deviationsTsne, I get this warning

tsne_results <- deviationsTsne(dev, threshold = 1.5, perplexity = 10,
shiny = FALSE)
Error in Rtsne.default(t(mat[ix2, , drop = FALSE]), perplexity = perplexity, :
Remove duplicates before running TSNE.

I tried looking at the matrix manually and removing motifs with duplicate expression and then rerunning from matchMotifs(), however, am still getting the same error even though I can no longer identify duplicates in my assays(dev)$deviations object. I am also able to make a Tsne manually using Rtsne(), but would love to play with the shiny output that is incorporated in your vignette. Any ideas on how to go about addressing this? Thank you.
