FIX: Remove trace by default

[larsoner]

Allows for discarding the trace, and making it the default behavior. It generally seems to be nuisance (non-)data in the analysis process.

Coverage increased (+0.0%) when pulling bafe40e on Eric89GXL:remove-trace into c54080f on nipy:master.

A test to check you removed the correct volume?

[matthew-brett]

No problem with putting in the release. I'm still writing docs, so another day suits me OK.

[larsoner]

Cool. I'll try throwing Appveyor in here, too. :)

[larsoner]

Okay, Travis and Appveyor are happy, and I made the test more comprehensive. Ready for review/merge from my end. The badges I added to the README should update after merge. If you don't want them there, I can remove them.

[matthew-brett]

I think the install_python.ps1 file should go in tools rather than nibabel-data.

Any way we could submodule that file to keep up to date with Olivier's changes?

A bit 50:50 on the travis badge, because travis-ci is so unreliable, can fail and give us bad press when there's nothing wrong.

[larsoner]

Hah:

I'll undo github-multi-status while I'm at it...

[larsoner]

I trimmed the install_python.ps1 file down a bit from what they had originally. One problem with submoduling this one is that they could switch to using system python instead of miniconda (which was an option in their original version), which would screw up our appveyor.yml file commands :(

[larsoner]

WDYT about keeping the Coveralls badge? 94% is awesome. But I guess if Travis goes wrong, you might get that one messed up, too...

[matthew-brett]

Coveralls badge is fine, totally agree about the 94% !

Do you think it is possible to get the appveyor commands working for Python.org Python? It's the Python most people are likely to be using...

[larsoner]

Yeah, the drawback is substantially increased testing time because numpy, scipy, etc. will need to be built. Or we'll have to set up wheels, which I don't really know how to do. Maybe leave that for a subsequent PR when you're feeling bored? :)

[matthew-brett]

I can't practically futz with the web stuff from here I'm afraid, but sure, miniconda considerably better than nothing, thanks again. Last I heard on this :

• [WIP] configure Windows CI with AppVeyor numpy/numpy#5328
• mingw-w64 builds of numpy. numpy/numpy#5194 (comment)

Coverage increased (+0.01%) when pulling 9841c41 on Eric89GXL:remove-trace into cf4e25e on nipy:master.

[larsoner]

Alright, Travis and Appveyor are happy, and I kept only the Coveralls badge. Ready for review/merge from my end.

[matthew-brett]

Thanks, merging.
