### t-distributed stochastic neighbor embedding (tSNE)

The panel depicts a plot of tSNE. The parameters **Perplexity**, 
**Number of iterations**, **Number of retained dimensions in initial PCA**,
and **Output dimensionality** required for the tSNE algorithm can be
set with the sliders. For the parameter
**Number of retained dimensions in initial PCA** the panel 
*Principal components* can be employed that shows on the left panel a 
Scree plot of the data set and permuted values and corresponding p-values
from the permutation. 

The different dimensions of the transformed data can be displayed by changing 
the values in the drop-down menus for the x-axis and y-axis (either two or 
three dimensions according to the **Output dimensionality**).
