Dear Authors,

I have now had time to evaluate the reviews and read your manuscript in detail, apologies for the slight delay.

This is a very interesting, well-written and well-illustrated paper, and I look forward to seeing it published in SE. Before I will recommend it for publication and in order to ensure the reproducibility of your work, I would ask you to provide the numerical details of your segmentation choices - that is, for the uCT data, the threshold values and the bit depth of your data as well as details on the reconstruction algorithm you used. Given that the ML segmentation hinges on the training of the classifier, I would ask to make the classifier file you used for segmentation available as supplementary material. In order to evaluate the influence of phase contrast on your synchrotron data, it would be important that you provided the sample-detector distance.

Please also have a look at the attached, annotated pdf.

With kind regards,
Florian Fusseis
