mnc2nii error - "floating point exception (core dumped)"

[KarissaChan1]

Some of my MINC DWI files get the "floating point exception (core dumped)" error when trying to convert to NII using mnc2nii, but others don't. Looking through the data, there doesn't seem to be any differences in data type between volumes that show the error and those that get converted successfully. Anyone have any suggestions on what might be wrong and how I could debug this?

Hi, to help here we'll need what version you're using, how you installed it, and preferably some example data of working and non-working.

Hi Gabriel, I tried it with the two most recent versions of the VM found here: https://packages.bic.mni.mcgill.ca/virtual-machines/
I ran a python script from command line in the VM to batch process my data. I've linked a OneDrive folder with 2 MNC files: one that gave the error that I named with "FLAG" at the end of the filename, and the other that didn't with "Working".

Probably the same bug as #90, got fixed in 1.9.17

I will look into updating the VM.

In the meantime, you could download the .deb file here, https://bic-mni.github.io/#v2-version-1918, install with dpkg -i inside the VM and source the new installed version to get the up-to-date converter manually.

Great, thanks so much. I installed the new version, and it worked fine with about half of my files, but for the other half I got another error:

I can't seem to figure out what's wrong with those input files (they're from the same dataset, same scanner, same centers).
