I added the possibility to define group-specific penalties and some more general tests. Also, the two classes are merged back to a single one (GroupL1). For the moment I added...

It seems like my changes to how the B matrix is built broke everything. I'll look into it. For the dense matrices case it works, anyway.

The problem was in a test where the group sparsity was used with overlapping groups. I added a separate class for that case to keep the two worlds separate as...

Sorry @fabianp , I've been offline for some days. I removed the test because I have misunderstood the suggestion to avoid the overlapping groups case. Speaking about that test, I'm...

Hi, I'm a heavy user of the group L1 penalty and I'd be happy to help with implementing it in copt. I've already done a similar contribution for another package...

I've never liked that trick in general. In this context it may work since the parameter range for volume fractions is `[0.01, 0.99]` and I guess that in the optimization...

Yay we celebrate issue # 100 !

@villalonreina please correct me if I'm wrong. You get the ICVF from the single-tissue Stick+Zeppelin (SZ) model of step1, and you fix the computed ICVF right into the multi-tissue Stick+Zeppelin+Ball...

These are the requirements. ``` ??? example "insert software name - insert short description" - [code repository](insert GitHub or GitLab URL ) - [website](insert URL) - [documentation](insert documentation or wiki...

Hi @TMNir ! Using BundleModel forces the orientation of the compartment to be equal, but the diffusivities and the other parameters remain untouched. Please @rutgerfick correct me if I'm wrong...
