In DASCore, transformations are operations which change the units of a patch. For example, applying a real Fourier Transform to the time dimension of a Patch. Transforms can be found in the transform module or access via the Patch.tran attribute.

import dascore as dc

patch = dc.get_example_patch()

transformed = patch.tran.rfft(dim="time")
# note how the dimension name has changed
# as have the units
