Question

[sana777munquad]

Hi, Currently i am using support vector machine for that I downloaded the RNA-seq geo dataset consist of normal vs cancer samples and I got a matrix of 4000 genes vs 58 samples consist of cancerous and normal samples. I unable to add the class label the coloumn. and what are the preprocessing steps is required for the support vector machine for doing classification between normal and canacerous?
