Can any one suggest which is the best clustering algorithm to check the coexpression of genes. I used the K-mean clustering algorithm but I suspect it does not cluster correctly.
I have microarray data for total 10 samples from different conditions/tissues. When I cluster data from all the 10 samples then it gives different results than if I cluster data for just one sample. Means, in both cases same genes are clustered in different clusters. Some variation I can expect but results are entirely different in both the cases.
Please help I am new to this.
