plotDataHeatmap() error with correlation but not with euclidean distance about mofa HOT 2 CLOSED

Hi Jane,
could it be that there are two many NAs in the data to cluster? Try do the same plot without clustering and you should be able to see it.

Best,
Ricard.

P.S. We have recently released MOFA v2 (https://github.com/bioFAM/MOFA2). Although there are novel functionalities, you can still train MOFA v1 models (but faster and with better downstream analysis functions).

Thank you for your answer.
I did the same plot without clustering (cluster_rows=FALSE, cluster_cols = FALSE) and got no error.
Also, I did the same using clustering on columns only and this is also fine.
But clustering on rows leads to the same error. Which does not held anymore if I use Euclidean distance.

I do not understand why the clustering on columns only is fine and not on rows.
Neither why does it change depending on the distance. Computing Euclidean or correlation distances across genes or across samples give differences...

Thank you for mentioning the v2, I might take a look at it in the near future
