Problem

[jkjk2]

I tried to build the SOM for the data set of 26 samples of 5 variables each (26 x 5).
If I test the msize=[9 6], everything looks OK (see Figure)

But, when I change the size, for example msize = [9 9], than some data go outside the SOM (see Figure below)

Similar results I observed, using the example of clustering the metals which are given in the SOM Toolbox manual. If I change msize, some points go outside the SOM.

Does anybody know, where is the problem?
Best regards,
Jan

Which version of MATLAB are you using? I have understood that the newest versions break some functionality that the toolbox relies on, but this is the first time I've seen this. Unfortunately, I do not have access to any MATLAB at the moment, so the help I can provide is limited. Could you provide the code you used? Maybe there is somebody else following who could lend a hand.

I use Matlab R2014b.
Enclosed is the code of my problem (‘SOM_HS.m’)
I also enclose the code from the SOM Toolbox manual (example of metals’ clustering) which produces similar errors for different SOM size.
Thanks, Jan
