Self-organization map

Hi everyone,

I have a question here. I have data for creating SOM map, and first steps it seems to be fine, but when I did for normalization of SOM, I have an error (you can see it below- in the Bold words).

Anyone know this error, please tell me how can I fix it?

Thank you so much in advance!

>> %% NHAP DU LIEU

>> sD = som_read_data('C:\Users\quang\Desktop\Data.txt');

Warning: Automatically determined data dimension is 8. Is it

correct?

> In som_read_data (line 187)

data read ok

>> %% XU LY DU LIEU

>> sD = som_normalize(sD,'range');

>> %% HUAN LUYEN DU LIEU

>> sM = som_make(sD);
