Dear Sara,

thank you very much for your feedback. It is greatly appreciated.
The current version the toolbox (1.12) does not support importing design files. We will try our best to add this functionality in a future release.

The second problem that you are describing (no convergence) happens every now and then and is hard to predict. When running a reproducibility analysis for a number of different dimensions, we have an output called no_convergence_error.png indicating, how many of the ICA repetitions for a certain dimensionality did not converge. In general nonconvergence is a hint that the chosen dimensionality does not describe the data well enough. I would exclude those dimensionalities for further analyses.

Hope that helps!

Florian
