Okay, that's good to hear.

I'd still like to know how what source this is: all of Teem? Just NrrdIO?  The NrrdIO that's part of ITK?

If there was a URL you used to get the source that would answer the question, and help me decide if there's a bug that needs to be fixed, and how to fix it.

Hi Gordon,

I actually fixed this already, by forcing QNANHIBIT value to 1 in CMake myself. Without doing so, I ended up with a project with the property value set to 0.

I used the latest CMake ( to create a 64-bit Visual Studio 2013 project (of NrrdIO 1.11.0) in Windows 7 x64.

Best regards,

Can you describe exactly how you compiled this?  And how you got the source to compile (was it all of Teem or just the subset called NrrdIO?)

If you are compiling all of Teem with CMake, it should learn the correct value of qnanhibit at configure time.  Since that doesn't seem to be the case, I'm curious what the configuration was.

Hi all,

I am using the latest version of nrrdio. It works fine for writing files, but there seems to be a problem with reading files I've just written.

The particular issue is with sanity check failure.
AIR_QNANHIBIT (which is 0 by default I believe) does not coincide with its run-time value of 1.

In particular, in sane.c, line 102,

AIR_QNANHIBIT != (int)mant

returns true.

What could be the cause of this? And what can I do about it?

The target machine runs Windows 7 (x64) and Visual Studio 2013 (I tried Intel compiler as well, same issue). The target application is also 64-bit (basically, 20 lines of code copy-pasted from nrrd file loading tutorial).

Any help is appreciated!
