Incorrect spacing when writing sim_map to disk

[samokhinv]

Hi, I am using your tools.demo* and noticed following read_image from tools.utils returns as a third element a ratio instead of spacing of the normalized image This output is passed as norm_info further, and eventually used to set spacing for dumped images.

Hello, take demo.py as an example. If you set the write_sim=True in pt2_normed, score = get_sim_embed_loc(emb1, emb2, pt1_normed, (im2['shape'][3], im2['shape'][1], im2['shape'][2]), norm_info=norm_info_2, write_sim=True, use_sim_coarse=True). This will generate an img.nii.gz file as well as its similar map file sim_map.nii.gz.

Yes, the spacing is not the same as the normed image input to the model, but they have the same aspect ratio, which is enough for visualization purposes.

single point template-query matching

correspond similarity map sim_map.nii.gz and the output query img.nii.gz
