Hi I have a list of protein measurements that have a wide spread (usually on the higher end)- inorder to compress the dynamic range to look at correlations with other parameters, I want to convert it to a log2 scale (primarily to be consistent with how someone else had analyzed it). I see natural log and log10 options in the formula transfrorm but none for log2. If I try to manually edit the formula from log[x] to log2[x], it throws an error. Any ideas to be able to do this? Thanks.

The formula is: Log(:Column, 2)

In the formula editor if you select "Log" then you see one spot for the column name. After you enter the column click on the ^ (in the top bar of formula editor) and a subscript "10" will magically appear, you can then click on the 10 to replace it with a 2.

TRR21,

I am getting a bit picky here, but you marked your response indicating "Thank You" as the solution. Karen's answer is what needs to be marked as the solution, so the users can go directly to the solution, and so that Karen gets credit for the solution.
