[Bug]: Incorrect`_frames_per_slice` attribute in `ScanImageTiffSinglePlaneImagingExtractor` results in incorrect video indexing #293

Closed weiglszonja closed 8 months ago

weiglszonja commented 8 months ago

What happened?

I'm using the ScanImageTiffSinglePlaneImagingExtractor read the TIFF files that we received from Dombeck lab. I have noticed an issue where the _frames_per_slice attribute does not correctly reflect the actual number of frames in a TIF file. I have 8 TIF files, each have 4000 frames with single channel and single plane. The _frames_per_slice attribute indicates 32000 frames which leads to incorrect indexing when accessing the video in .get_video().

I'm not sure how the example files look like that these changes were based on, but in this case, adding 

self._frames_per_slice = min(self._frames_per_slice, self._total_num_frames)

would solve this discrepancy. I'm happy to discuss this and open PR to fix, @alessandratrapani @pauladkisson

The legacy ScanImageTiffImagingExtractor works fine with these files.

Steps to Reproduce

from roiextractors import ScanImageTiffSinglePlaneImagingExtractor

# an example TIF file from Dombeck
file_path = ".../230817_00001_00006.tif"
extractor = ScanImageTiffSinglePlaneImagingExtractor(file_path=file_path, channel_name="Channel 1", plane_name="0")
video = extractor.get_video()

Traceback

Traceback (most recent call last):
  File "/Users/weian/catalystneuro/roiextractors/read_scanimage.py", line 6, in <module>

Thanks @weiglszonja, can you send the metadata as its extracted, so we can take a look to see if there are any fields we can use to catch this?

weiglszonja commented 8 months ago

Sure, thank you @pauladkisson. Now that I'm also looking at it, there is a field "SI.hScan2D.logFramesPerFile": "4000" that could be probably used to catch this. What do you think?
