This code is specifically designed to open JPK AFM files (images and force curves) and import a number of parameters used for the scanning.

In the case of images:
Two structs are created, one containing all the channels of the image (they are calibrated in the case of vertical deflection) and a second struct with a number of key parameters of the scanning. These include: Origin, scan angle, length and pixels of the scan, I & P Gain, baseline, set points vertical sensitivity and vertical stiffness of the cantilever used.
If metadata is corrupt, or tip is not calibrated will return values in RAW form.

Please read function Help for further details.

Tested images were multiple all with calibrated tips, working in contact mode and AC mode. QI-mode images still not implemented.
