@oesteban - for freesurfer are we including the entire image or breaking out pieces?

[oesteban]

@satra entire image

[oesteban]

Can we leave dcm2niix and VTK for another PR?

As regards FreeSurfer, is there any place where I can find a lightweight version? (BTW, this upgrades FreeSurfer to v. 6.0.0).

[oesteban]

Question:

We have these two docker build commands in the circle.yml:

    - docker build -f docker/Dockerfile_py27 -t nipype/nipype_test:py27 . :
        timeout: 1600
    - docker build -f docker/Dockerfile_py35 -t nipype/nipype_test:py35 . :
        timeout: 1600

They take ~3 and ~1 min respectively but they are not cached. Do we want to cache them?

[satra]

does circle rebuild cache if docker/Dockerfile_py[27|35] changes? if so sure.

[oesteban]

Yeah, it rebuilds, I'll add caching for them.

[oesteban]

@satra what did you have in mind about freesurfer?

[satra]

@oesteban - freesurfer has many components and expands out to over 8G. if we just want it for recon-all, we can strip it down to about 500MB. if we want tracula, and cvs, and other tools, then it will grow.

if circle can handle it, i say we don't touch it right this minute. but for anyone who wants to test it that docker download will be close 15G, no (with FSL and FreeSurfer and AFNI)?

[oesteban]

5 GB - https://hub.docker.com/r/nipype/nipype/tags/

[satra]

don't worry about it right now.

[oesteban]

merge?
