Seg3D file saving has been cleaned up in this version. In older versions, you could select a file type to save as or export to, but if you did not manually put on the correct extension, you could not read that file back in with Seg3D. Now, when you select a particular file type, Seg3D will ensure the proper extension exists.

When I changed this behavior, I used the existing file extension selection choices from earlier Seg3D versions and left the default selection as NRRD format. However, you can be still save any file type by selecting the All files (*.*) choice and then adding whichever file extension you like including .mha .

Would it make sense to change the default file type to All files instead of NRRD to more closely match the previous behavior? I can also make the file choices match those available in the Load Volume dialog so that it is more clear that this file type is supported.

Please let me know if you are still unable to export in a particular file format.

I'm running Revision 44484 of the development branch, and it seems that it's no longer possible to export a segmentation to MetaImage format (.mha). Is this intentional?

To reproduce, try to export, and click on the file type menu. There's no MetaImage option. If one tries to give the file an .mha extension, it gets renamed to .nrrd.
