Hi, I'm in the Visualize Results section of this code and I can't seem to get the visualization of the results.

https://github.com/nel-lab/mesmerize-core/blob/master/notebooks/cnmfe.ipynb

Code:

a = LazyTiff(df.iloc[0].caiman.get_input_movie_path()) a.shape

Error:

---

AttributeError Traceback (most recent call last) Cell In[25], line 1 ----> 1 a = LazyTiff(df.iloc[0].caiman.get_input_movie_path()) 2 a.shape

Thank you in advance.

Not all tiff files support lazy loading, you will have to convert them to be lazy-loadable if it doesn't work. You can use tiffit: https://github.com/EricThomson/tiffit

Yes, that worked, thank you.

I noticed there was a typo in the cell immediately after, tiffile.memmap should be tifffile.memmap. Thank you and hopefully this helps you.
