Supported raw data

Pingwyn current supports loading and parsing the following SPM data types:

• Gwyddion (.gwy)

• Plain text (.csv)

• Pingwyn pickles (.pg_pkl)

• Omicron Matrix (.Z_mtrx, .I(V)_mtrx, etc.)

• Bruker SPM (.spm, .pfc)

Data can be stored in a few formats:

• Gwyddion

• Plain text

• Pingwyn pickles

See pingwyn.save() for more information.

Warning

Loading and saving data in Gwyddion and plain text formats is lossy. (Meta)data that does not have a Pingwyn counterpart (such as Gwyddion scale bars, plain text comments or unimplemented machine-specific metadata fields) will not be stored in Pingwyn objects. Thus, when the object is saved, this (meta)data will be lost.

Loading from and saving as Pingwyn pickles is the only way to have lossless data transfer.
