neurodebian cmtk depends on sri24-atlas
Recently we have been setting up continuous integration with travis for a CMTK-dependent R package.

https://travis-ci.org/jefferis/nat

We are installing cmtk from neurodebian. Unfortunately 90% of the build time is spent downloading 60Mb of sri24-atlas, which is irrelevant for our tests. It appears that cmtk depends on sri24-atlas but I don't see why it should (I would have thought sri24-atlas would be a suggested package). Is there any reason for this dependency? Was it discussed at the time of the neurodebian package creation? Is there any way I can avoid it?

I guess I should also ask on neurodebian-users.

Many thanks,

Greg.

Answering my own question based on a response from Yaroslav Halchenko on neurodebian-users

This specific setup can be simplified by using a script by neurodebian. See https://github.com/jefferis/nat/compare/...

For some reason I thought this was a strict dependency, but it was just recommended so this does the trick:


sudo apt-get install cmtk --no-install-recommends
