# Perform the PCA

The way to perform this analysis is rather simple through {{uranie}}: simply provide the {{ds}} that 
contains data to an `TPCA` object, only precising the name of the variables to be investigated. This 
is exactly what's done below:

{{  
    "```{literalinclude} " + parent_dir 
    + "/roottest/uranie/doc/dataserver/use_cases/" + language + "/dataserverPCAExample." + extension + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc[language] + "\n"
    + "```" 
}}  

Once done, the process described in the {{metho}} is finished and then interpretation starts.
