Manual movie cropping with modelModifyMovies¶

If users need to eliminate specific regions of their movie before running cell extraction, that option is provided. Users select a region using an ImageJ interface and select done when they want to move onto the next movie or start the cropping. Movies have NaNs or 0s added in the cropped region rather than changing the dimensions of the movie.

This is generally advised for movies such as miniature microscope movies imaged through a GRIN lens probe where the outside or edge or the GRIN lens are visible. This can lead to large fluctuations that can throw off some algorithms (e.g. PCA-ICA can end up assigning many components to these "signals").
