Is k = 2 the only difference @changt34x ? Are they like this for all datasets? Its possible that the different subsetting steps (new common_genes
) performed by @amyecampbell altered the cluster assignment numbers
I haven't compared all of the samples (due to the change in ordering or addition/removal of samples between the current version and the paper) but from a random set of comparisons it only affects k=2 for kmeans and NMF, but not any other.
Clustering results using k=2 clusters, for both kmeans and nmf, do not follow into clustering results for k=3 or k=4 clustering. When looking at clustering results and comparing k=2 to k=3, very few samples in k=3 remain in their k=2 cluster.
Additionally, when compared to Way et. al. 2016, clustering for k=2 appears reversed in Supplementary Table S3. Samples placed in cluster 1 in this analysis appear in cluster 2 in the published paper.
