Change demo image in documentation

Throughout the documentation, we give examples using test_segmentation/test_sem_image/image1_sem/77.png, however I don’t think this image exists anymore.

I think we should instead change it to AxonDeepSeg/models/model_seg_rat_axon-myelin_sem/data_test/image.png, which is the SEM test data set, and also change the resolution accordingly in the examples from -s 0.07 to -s 0.13

The image still exist in the test_segmentation folder, the link to download it is in the doc here.

As you mentioned, all of our examples are based on the test_segmentation folder. In particular, our examples for segmentation and morphometrics cover different scenarios which require “multiple folders” or “multiple images”.

Ahh, while I was searching for it, I did a ctrl-find, and missed this.

I think at the very least, maybe we should automatically download it, because not every user will re-read the entire documentation, and thus may miss it. For example, I was only interested in the zoom factor today, tried running the example command, and it failed, and clearly it wasn’t obvious to me I had to scroll up all the way on top to find where to download it. I think our examples should all “work out of the box” as much as possible.

Ah gotcha. We already have some of those scenarios in the testing dataset (which is also downloaded); maybe we could include these as separate folders there, and then just change the path to them in the doc?

Yes, that would be great!
