How to Log-Transform the data?

Hi everybody,

Have some troubles with my data while trying to use OLS and then The Exploratory regression. The report interpretations tell that I should try to transform some skewed variables. I've seen that advise a few times in Help too. But I haven't found the tool that permit to do that. As I understand  - I need a log transformation (Histogram tool showed better result with it). So how should I "log-transform" my data. Geostatistical Wisard creates some rasters as I understand, and I need to get new (log-transformed) values in the attribute table for using them letter in OLS again.

Could anybody help with some advise?
