#32 Zero (0) value is shown as 1.0 colour

Data Model (2)

The colour of 0 values are shown as same colour as those 1.0. So for example if I load a matrix that contains values in the range of 0 (green) to 1(red) and then visualise them all the cells that are 0 are shown as red. This is very confusing!

Example attached.

    Hey there,

    I've put together a fix for this bug and posted a development version of it to this location: ftp://occams.dfci.harvard.edu/pub/bio/devel/mev_snapshots/MeV_4_7_0_r2600_win.zip

    Would you mind giving it a try?

    I just tried. Still not working.
    The main problem is that during statistical analysis (i.e. T TEST) MEV consider the value as 1 and not 0 (zero)! Means: wrong mean values, wrong sdt dev, wrong "significant genes"! You can see it ones you download the resulting cluster table were all 0(zero) are substitute by 1.

    I have the same problem with the zero values. I have tried version 4.1.02, 4.4.1, 4.5.1, 4.6.2, 4.7.1 and the one included here in Windows and they all work the same for me.
