LesionFilling seems not to save the resultant image.

I was running LesionFilling command on Linux VM (Xubuntu VBox).
It is a very simple and straightforward script, but I got an error message shown below:
"""
Number of lesions: 174
./WML_filling_counting_labeling_volume-recording_Data_since_2019.sh: line 18: 21602 Floating point exception(core dumped) ${ANTSPATH}/LesionFilling 3 ./${i}-pre-denoised-T1W_0p5.nii.gz ./${i}-FLAIR_WML.nii.gz ./${i}-lesion_filled_T1W_0p5.nii.gz
'
"""
And the result (supposed to be a lesion-filled T1 image) was not saved.

I would like to know what may cause 'Floatingpoint exception(core dumped)'?
Are there any conditions for input data? (nii.gz or nii etc.)

Thank you,
SC

Floating point exception suggests a problem with the data, would you be able to share it?

Thanks for your reply. I finally acquired permission to share two files (T1W and WML mask images).
Could you let me know how I can share them with you (any cloud service that I can upload them safely or email address so that I can send you a file link)?

Thank you

I uploaded two sets of images that issued (attempting LesionFilling command on Xubuntu Linux environment) the same type of error messages without resultant lesion-filled images. Other images from the same pool of batch-processed data were successfully lesion-filled while but a few of them were not with that floating-point error.

Thank you.

Thanks - I think there is a divide by zero happening somewhere. I'll work on a fix for LesionFilling.

In the meantime, is there any similar implementation (in ANTsR or ANTsRNet) of LesionFilling so that I can use it instead of LesionFilling (in ANTs)?
