Hi @cyanching did you manage to solve this, or is this still an issue?
Hey Frosina, I hope you have been doing well! :)
I am very sorry for the late reply, I have yet to test DeePiCT again when we will have new imaging data containing microtubules. Then I will let you know how it'd go! And after updating mrcfile to the latest version, it reads cryoCARE-generated headers without any complaint.
Cheers,

Hey Frosina!
I hope everything's going well with all your projects and life in general! :)
I just downloaded a tomogram from the following dataset: https://www.ebi.ac.uk/empiar/EMPIAR-10989/, 00004_sq_df_sorted.rec from the 'tilt series stacks and metadata of cryo-electron tomograms acquired on RPE1 cryo-FIB lamellae' section. I suppose this tomogram and its segmentation results were used to train DeePiCt?
Though after directly plugging it into the DeePiCt_predict3d Colab script with default parameters, the post-processing step returns the following instead of generating clustered and cleaned results:
Processing tomo test file in .mrc format Region mask: no_mask masking_file: nan No intersecting mask available of the type no_mask for tomo test. /content/DeePiCt/3d_cnn/src/tomogram_utils/coordinates_toolbox/clustering.py:21: FutureWarning:

. It will be removed in version 1.0. Please uselabel_image
instead. labeled_clusters, num = morph.label(input=dataset, ^CThough after converting this 4-binned tomogram into 8-binned (binvol in IMOD), the post-processing step went through but the segmentation results are null or far-off (no microtubules, or other structures were segmented throughout the slices or the segmentation appear as random blobs):

And I replicated the same error with two of our own tomograms. Do you maybe have a solution around this issue? Are there additional processing steps (I made sure to denoise and perform spectrum filtering on the tomogram) or parameters to tune to get correct segmentation with the models?
An additional note: when I plugged in binned tomogram generated using Dynamo, DeePiCt complained the file was not in mrc format and could be corrupted.
Thank you so much!
