Hi -

For the files that don't load: could you attach them to this bug report, and could you provide the steps you used to create them?

Thanks

Sorry, its my mistake, the file size is 6Mb (a slightly bigger of limit).
This file is placed in
http://www.spl.harvard.edu/publications/item/view/1180
Tumorbase.zip on the bottom of the page. After unzipping, please see case1 folder or any other case from this dataset.
Moreover, this error appears even in case I trying to load the file that just has been saved from Analyze or DICOM formats in nrrd format using Slicer4 menu.
Thank you for you attention to my problem.

I was able to read greyscale.nrrd on Windows fine.
Steve, can you try on other systems?

I was just looking at this too - I was able to load all the files that I tried on a mac using slicer 4.2.2.

bks_2005: can you give us any more clues on how to reproduce the issue?

I use Ubuntu 12.04 LTS with latest update. This error appears only in the Ubuntu in different computers and Ubuntu configurations.

Steve, could you take a look or reassign to somebody with an access to Ubuntu

I tried loading nrrd volumes from the tumorbase data on a ubuntu 12.04 machine and had no problems.

Are you sure there's not something else going on? Do you get any diagnostic information in the error log window?

Since this tested okay on my Ubuntu (12.04) installation there must be something else going on. Do you have an ITK_AUTOLOAD_PATH or something similar set in your environment?

Ok, I am grateful to collegues! The ITK_AUTOLOAD_PATH variable is not defined in my enviroment. I think it must be path to ITK shared libraries location.

Yes, it may be something else in your path. If you run the following in the slicer python console it will show the environment and maybe we can debug with that:

import os; print(os.environ)

Most of the values are set by the slicer launcher.

Here's what I get on my Ubuntu 12.04 machine:

Had the same Problem with the stable Version. The nightly build works for me.
import os; print(os.environ) print nothing in both Versions.

best regards

Reporter confirmed that it was fixed in a nightly version.
