    Hi there,

    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).
