Clustergram Bug? - Different dendrograms produced by Clustergram vs SPSS and pdist -> linkage -> dendrogram using the same parameters

1 view (last 30 days)
Good Afternoon,
I have tried already all different 'data processing' parameters of clustergram in order to get the same dendrogram that is obtained with pdist -> linkage -> dendrogram without any luck.
I also double-checked the results obtained by SPSS with the same data and parameteres used by pdist -> linkage -> dendrogram and the dendrograms are consistent.
Therefore I conclude is definitely something related with the clustergram class.
Could it be possible that there is a bug or something like that with that class?
To whom I should direct this question in order that it'll be further evaluated by the developers of clustergram?
Thanks in advance,
Diego

Thank you Oleg. I'll try the latest version first. It seems strange to me that there are not other complains about this, so chances are that the class is ok and it's just me. Thanks again, Regards, Diego

I think I have the same issue. I use pdist-linkage-dendrogram, then I use clustergram, the results are different.

I believe this is a bug and in 2013a they fixed this bug. I confirmed this by running my code on 2013a, and two function give the same cluster.
