Hi Arun,

I have a question about choosing a subset of data.
I have a matrix of 5000 in 3500.
I want to choose specific variables such as proc1 to proc1000 and Lab1 to Lab1600 and put it into a new matrix to run some correlation analysis.
Since I have 3500 variables, I don't know from what column my lab or procedures start.
I really appreciate your help.
Thanks.

 
Best,Farnoosh Sheikhi
