[Spm] plane subraction in Nanoscope or WSXM software

[mbrukman at seas.upenn.edu]

Users,

Is there a way to learn what plane-fitting parameters either DI  
offline image processing or WSXM has applied to data? While we always  
save our raw data, we sometimes need to plane-subtract during analysis  
to find data of interest before we can try to interpret it. In order  
to draw the averaging box, we first need to reduce the dynamic range  
of the screen image to something our eyes can use. But once we're  
done, we need to manually undo the offsets and slope correction to get  
our absolute values back.

We typically use native DI Nanoscope applications or WSXM, so does  
anyone know how to extract the fitting parameters from either of those  
two programs? WSXM has appears to have the added problem of performing  
a plane subtract immediately upon importing files. So we'd like to be  
able to undo that, as well.

Thanks!
Matt
