clustergram does not recognize my data as a datamatrix???

i am trying to create heatmaps using the"clustergram" function...i imported my data, matlab removed the row labels and column lables into a sperate file called "textdata", leaving me with a file called "data" that contains rows of standardized expression data. i typed "x=clustergram(data)... and received an error message stating that my data must be a numeric matrix. when i look at the data file, i see numeric data in rows and columns... WHAT AM I DOING WRONG? as always thanks for the help jb

i opened the "data" file and created a new variable, 'Y'. i then typed X=clustergram(Y) and out popped a heatmap...YAY!!!! i then opened the "textdata" file and created 2 new variables for the column of row identifiers(Z) and the row of column identifiers(A) using the set function i wrote..."set(X,'RowLables',Y,'ColumnLables',A) these 2 lines created and labeled the heatmap construct for me.....NOW how do i import the heatmap out of MATLAB???
