Studio should not let us set the PCA mode to greater than number of samples - 2

This should be number of samples - 1 (not 2)

@sheryjoe , are you sure? We are using 0 based numbering for PCA modes. A model with only two shapes has only mode 0 (n-2). With 3 shapes, 2 modes (0 and 1).

[sheryjoe]

You are right, I forgot about the zero based numbering (might be confusing already for users? ) -- effectively max number of modes = number of samples - 1

[akenmorris]

I don't mind if we use 1-based numbering for modes. Just say the word.

[sheryjoe]

I think 1-based is more intuitive for users (first mode, second mode ... etc). Let's change it to 1-based then, thanks.

[akenmorris]

Using 1-based now.
