I'm new to MeV. when I t try to save the expression matrix, I got small window said "java.lang.NullPointerException" : Can not save Matrix. I don't know how to fix it.
Please help me. Thanks.
Can you tell me where you are saving the matrix from? What is visible in the main viewer window when you save it?
Also, are you using MeV v4.5.1?
I use MeV v4.5.1.
I did adjust data (data filter, fold filter, gene/row adjustment, log2 transformation). After adjusted data, I go to FILE>SAVE MATRIX and try to save Matrix to my own computer folder (Window Vista). then I got error. The visible in the main viewer is heatmap (red /green graph).
