Hi

I was wondering if anyone can help?

I have six data diles and I want to extract different columns from all 6 files. The columns to be extracted from each file are in a table (t) as follows:

Filename Column number 1 Column number 2 Column number 3

A 35 101 173

B 82 132 211

C 74 149 258

D 72 137 200

E 131 187 236

F 62 123 200

Hi Lucy,

I understand that you would like to extract columns from data files which are in the form of table. I would suggest you to get familiar with different ways of accessing data in a table from here.

Hope this helps.
