You can use tiffs or PNGs or JPEGs. We use the image loader from scikit-image. Single plane images can read into data as nY x nX x channels or channels x nY x nX. Then the channels settings will take care of reshaping the input appropriately for the network. Note the model also rescales the input for each channel so that 0 = 1st percentile of image values and 1 = 99th percentile.
If you want to run multiple images in a directory, use the command line or a jupyter notebook to run cellpose.
Tiffs with multiple planes and multiple channels are supported in the GUI (can drag-and-drop tiffs) and supported when running in a notebook. Multiplane images should read into data as nplanes x channels x nY x nX or as nplanes x nY x nX. You can test this by running in python
import skimage.io data = skimage.io.imread('img.tif') print(data.shape)
and ensuring that the shape is as described above. If drag-and-drop of the tiff into the GUI does not work correctly, then it’s likely that the shape of the tiff is incorrect. If drag-and-drop works (you can see a tiff with multiple planes), then the GUI will automatically run 3D segmentation and display it in the GUI. Watch the command line for progress. It is recommended to use a GPU to speed up processing.
When running cellpose in a notebook, set
do_3D=True to enable 3D processing.
You can give a list of 3D inputs, or a single 3D/4D stack.
When running on the command line, add the flag
--do_3D (it will run all tiffs
in the folder as 3D tiffs).
