DOC: Slide instructions don't work as expected.

[arokem]

The instructions on this slide: http://nipy.org/heudiconv/#3

Do not work as expected. That's because

root@a3775bb9a427:/# source activate neuro && cd /dicoms
Could not find conda environment: neuro
You can list all discoverable environments with `conda info --envs`.

If you follow the rest of the instructions, you don't get the data into the right place, because once source activate fails, the cd /dicom is not executed.

Where is the source of these slides? I can make a PR.

[arokem]

In particular, I believe that the source activate neuro && can be removed with no consequences.

@arokem - before you update, i think there have been a few changes to the container as well.

@mgxd - can i delete latest from docker hub?

[mgxd]

@arokem thank you! there are a few outdated pieces, I was going to push my slides from the coastal coding workshop, but fixing up the current slides would be nice!

@satra - yep feel free to delete (i think anything besides unstable is fair game to remove). We will cut a new release soon and should be on DHub versioned releases from now on 😄

[satra]

@mgxd - i'll let you work with @arokem on who should be updating what. seems like its easier for you to do.

on the hub front i have deleted the old images. it would be nice to make a release, so that there is a fixed versioned image people can use.

I think it would be best if @mgxd took a first pass at this. I don't know enough about the tool to do anything cogent (which is why I was looking at the slides in the first place!).
