I am using a downloaded Slicer 4.9.0-2018-05-04 r27180. Using sample data MRBrainTumor1 and MRBrainTumor2, I try to register them using SlicerElastix extension. I tried a couple of presets (`3D MRI, monomodal (brain)` among them), but that doesn’t seem to matter. After registration is finished:

```
Volume registration is started in working directory: C:/Temp/User/Slicer/Elastix/20180523_093922_751
Register volumes...
Generate output...
Registration is completed

```

Nothing looks changed. If I try to save the scene, the transform and resampled volume are not selected by default, meaning they are empty nodes.

If I go to the temp folder and load the intermediate images (e.g. `result.hdr`), they are correctly resampled. Can anyone confirm this?

It works well for me with “generic (all)” preset? Have you tried with that?

`generic (all)` and `generic (rigid)` do work now, but I could have sworn they didn’t work earlier today. `3D MRI, monomodal (brain)` does not work in repeated tests. This applies both to 4.9.0-2018-05-04 r27180 and today’s nightly.

@Andinet_Enquobahrie was able to reproduce this on his computer. I submitted an [issue](https://issues.slicer.org/view.php?id=4562).

Issue fixed (input file format in the parameter file was set incorrect), should work in tomorrow’s nightly build.
