BUG: manual ROI extraction error

[EunJungHwang]

Describe the issue:

I have 2 channel (GC and tom) 2p data. When I added an ROI manually and tried to extract it, I got an error complaining that it needs "number of frames n_frames when writing file".

Reproduce the code example:

Used the GUI native feature.

Error message:

1 cells added to manual GUI
Masks made in 0.26 sec.
Extracted fluorescence from 1 ROIs in 83442 frames, 132.92 sec.
Traceback (most recent call last):
