Normalizing soft files using log based methods

Question

[f.dehghanian68]

I can read soft files in R using GEOquery. They are normalized, but we can't always tell how. Most of the times it's not in log. Can I normalize this data using other methods? Actually I normalize .CEL easily in R, but this dataset just has Soft and txt file. I need to normalize soft file using method in log? Is there any possible way to do this for example with RMA?

I used following command, but unfortunately the output file contains a lot of NA and -inf?

Is there any way to normalize GEO data in soft format?
