CNMF-E errors on movies with NaNs

The current codebase throws an error at
https://github.com/zhoupc/CNMF_E/blob/master/ca_source_extraction/endoscope/connectivity_constraint.m#L13
if the movie contains NaNs (as might be the case after motion correction when the borders are cropped with NaNs). Re-ran a couple of movies after setting the NaNs to zero and it ran fine without errors.

Is there a way to have CNMF-E automatically account for this when running movies (e.g. have a inputMovie(isnan(inputMovie)) = 0; % or mean pixel value) so we don't have to alter or duplicate existing datasets? e.g. updating `Sources2D.load_data' method? https://github.com/zhoupc/CNMF_E/blob/master/ca_source_extraction/%40Sources2D/Sources2D.m#L1073

good point. I added a line 211 in https://github.com/zhoupc/CNMF_E/blob/master/ca_source_extraction/%40Sources2D/Sources2D.m

Error still occurs on HDF5 movies with NaNs. Is there anywhere else in the code that the movie is called that would lead to this issue?
