Describe the issue:

We use suite2p to run segmentation on our motion corrected files. We set the arguments to run cellpose segmentation in suite2p as follows:

The weighted masks ops.npy file output contains a value of zero for the diameter. When loading this file into the suite2p UI, a divide by zero error is raised (see below)

Reproduce the code example:

n/a: Using UI
