[jasmainak]

I get the following error on the power example:

@annapasca it's asking for ica files. Where do I get them from?

I put sub-0003_task-rest_run-01_meg_raw_filt_dsamp_ica.fif in the Dropbox :)

hmm ... now my script is stuck. Output so far.

HI @jasmainak I have just run the power analysis and it works for me. I don't understand the problem.

@davidmeunier79 @dmalt some idea?

@annapasca did you try using my environment file that I provided in this comment? You can save it in an environment.yml and create an environment:

$ conda env create -f environment.yml

Then activate the environment and run the examples again ...

[jasmainak]

I suspect though that it's not related to the environment, just the data files. So, we should try to fix automatic dataset fetching. This is done in my pull request #30 . Let us test it and make it work ...

[jasmainak]

Okay I think this issue can be closed now.
