    Dear User,

    I tried to create SOM using microarray expression dataset in MeV. I have 3 different time points and 3 different genotypes on total 30 samples. I followed the instruction to upload the whole expression value dataset into MeV. It seems fine at the beginning, but when I tried to create SOM by clicking "clusters" and selecting SOM. Basically I followed the default setting in SOM, unfortunately what I got is the blue or blank nodes, I also tried to change the parameters, but it doesn't work.

    Could you please let me know if something is wrong with the process? how to do it?

    Thanks a lot for the help
