Dear all,
recently, when I open a spm file in Gwyddion, I find the unit of the Amplitude Error is wrong (see attached snaped image ). I am sure that during the measurement, the unit is in the mV, but not the V. Can someone help how to fix this?
I am really appreciate that if someone could help me.
Thank you for the report. I do not have that many files with AmpitudeErrors in volts (as opposed to metres), but you are right the voltage value scale is wrong. At this moment we do not know why or how to correct it to match Nanoscope. The conversion from raw data to physical values has to be done differently than for other channels (or even differently to when it is in nm)? On the other hand, these voltages are not something you would normally try to interpret quantitatively – do you actually need correct absolute values?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
