csv output of conservation does not include the percentage of the consensus symbol by default

From Jalview discuss (Hari Jayam: "Show values in Textbox" May 10th)

Hi I have a saved alignement generated from the clustalw service at EMBL-EBI.
When I launch Jalview from the clustalw site - I click on the
consensus and be presented with a "Show values in textbox" option
which then prints to a textbox the following information ( see below).
The second line of this information which indicates the consensus
sequence and the percentage conservation at that point.

This feature is however not available in jalview 2.5 . How can I open
any saved alignment in jalview 2.5 and obtain the consensus
percentage for each position in the alignment for use in another
downstream analysis program.

Thanks
Hari
