[Gwyddion-users] Processing Phase Data

[Haeberle, Tobias]

Hello,

I want to process some phase data from an AFM scan and correlate it with the topography data. Unfortunately, gwyddion can’t open the phase image (.tif format). I get the error:

`````
The type of data is unknown. Please report it to the developers.

Full file path: .../Img2015_1217_08404721_2INPUT_B.tif.

Loaded using: joel.
`````

The AFM is a JOEL system. I have no problem reading the topography data images. Or is there a misunderstanding on my part and gwyddion is not designed to look at phase data?

Thank you!

Best regards
Tobias

You can work with images of any physical quantity in Gwyddion. In this
case we need to know how to load the raw data for phase (or any other
channel for which you get such message). Currently we do not know. To
fix this it should be be sufficient to send me some phase image
*toegether with information what it should look like correctly*,
especially what is the value range
