To Calculate the top-table values
To visualize the different kinds of differentially abundant proteins, such as up-regulated, down-regulated, significant and non-significant proteins
By MA plot
By volcano plot
Both of the above plots give same result.
To obtain the overall differentially abundant proteins result
To find the up-regulated proteins
To find the down-regulated proteins
To find the other significant proteins
To find the non-significant proteins
