Hi 

I get the following error while loading dcm2niix in mac OS Mojave v 10.14.5.

dyld: Library not loaded: /usr/local/lib/libstdc++.6.dylib
Referenced from: /Users/postdoc/Mtools/MRIcroGL/dcm2niix
Reason: image not found
Abort trap: 6

It seems some library is missing. How do I troubleshoot this error? Do I have to download something else?

Thanks
Avantika

What version of MRIcroGL are you using? With Mojave I would recommend the latest release 1.2.20190410. I suspect upgrading will fix this issue. Alternatively, you can always grab the latest version of dcm2niix and replace the version that came with your version of dcm2niix.
