this function is not aware of "tiff squashing".

At XPD, we always use "tiff squashing" There is a key called "number_of_sets".

I do this change manually for py file here :/xx//site-packages/ophyd/areadetector/detectors.py

    #shape = (self.cam.num_images.get(),
             #self.cam.array_size.array_size_y.get(),
             #self.cam.array_size.array_size_x.get())
    #if proc plugin is being used
    shape = (self.number_of_sets.get(),
             self.cam.array_size.array_size_y.get(),
             self.cam.array_size.array_size_x.get())

The quick-fix is to over-ride this at XPD/PDF, the long-term fix is to push this method down into the plugins.

In addition to the squashing use-case, you could imagine there being two file writing plugins, one of them sitting behind a ROI plugin. There is no way for a detector level function to know what shape the final node in the processing chain is going to see.

I think @MehmetTopsakal has correctly identified the problem.

@tacaswell on a local conda environment, I was manually editing /xx//site-packages/ophyd/areadetector/detectors.py as shown above. But this is not ideal. Because I cannot edit files such as "/nsls2/conda/envs/2022-2.3-py39-tiled/lib/python3.9/site-packages/ophyd/init.py". Is there a way to apply this fix without editing source code? Thanks
