Good afternoon,

i'm working with OTB 6 on windows. 

I generated several OTB texture indices. Now, i want to evaluate the 
information 's redundancy thanks to a Principal Component Analysis. 

=> Is it possible to do that with OTB? The tool called "dimensionality 
reduction" would be interesting fot this step? 
Moreover, I would like set a mask AND set a spectral subset (in order to 
ignore some indices bands which seems no relevant to introduce into the 
process). 

Could you throw light for me? 

In advance, thank you very much for your help. 

Kind regards.
